Impact of fin and hybrid nanofluid on hydraulic-thermal performance and entropy generation in a solar collector using a two-phase approach

This research investigates the impact of cylindrical fins and a hybrid nanofluid (HNF) composed of water and copper-zinc oxide on the hydraulic-thermal performance and entropy generation of a solar collector (SC). Numerical simulations are conducted for steady flow utilizing the pressure-based solver. The HNF flow is modeled using the two-phase mixture approach, while the turbulent flow is represented using the standard k-ε turbulence model. The study explores varying inlet Reynolds numbers (Re) from 17,000 to 41,000, volume fractions of nanoparticles (φ) ranging between 1 and 3%, and cylindrical fin heights (λ) of 5, 10, and 15 mm. The results indicate that employing twisted tape in the SC leads to improved thermo-hydraulic performance compared to a SC without twisted tape. Also, the addition of cylindrical fins plays an important role in the flow field because the HNF flow separates after colliding with the fins. This causes the formation of swirling vortices and spatial and temporal fluctuations. The amount of the performance evaluation criterion (PEC) is similar in all cases and decreases with Re. The PEC is much higher than the desired one. Although this trend is decreasing, the results show that in this range of Re, the use of cylindrical fins creates a more reasonable pressure drop (Δp) compared to the enhancement in thermal performance. Finally, the thermal and total entropy generation are reduced and frictional entropy is enhanced by increasing Re. In other words, the increment in the height of the cylindrical fins in the solar system leads to a reduction in the entropy generation.

Convective Heat Transfer Enhancement using Novel Twisted Tape-A Numerical Investigation

Convective heat transfer and pressure drop characteristics have been investigated numerically in a tube fitted with a twisted tape and a modified twisted tape. A novel geometry of the tape with lateral projection and without lateral projection is introduced for comparison. The results obtained from ordinary twisted tape are compared with those of the Modified twisted tape with lateral projection and modified twisted tape without lateral projection. The experiments reveal that the pressure drop is lower in the modified twisted tape without lateral projection than in the modified twisted tape with lateral projection. However, the Nusselt number in the modified twisted tape without lateral projection is slightly lesser than in the base case with ordinary twisted tape. The Nusselt number in the modified twisted tape with lateral projection is higher than the ordinary twisted tape because the lateral projection diverts the fluid towards the boundaries, and the thermal performance factor is increased. Thus, the Modified twisted tape without lateral projection increases the thermal performance factor to 1.0065 by decreasing the pressure drop, and the modified twisted tape with lateral projection increases the thermal performance factor to 1.1584 by increasing the Nusselt number.

Pressure drop reduction of the impeller spiral static mixer design enabled by additive manufacturing

A new spiral static mixer (SSM) design, also known as helical or twisted tape mixers, called the Impeller SSM, inspired by centrifugal pump impeller blades and fabricated by additive manufacturing (AM), is presented. The pressure drop and mixing efficiency of an Impeller SSM are compared to the standard SSM. Both the pressure drop and mixing characteristics are measured experimentally and validated by computational fluid dynamics (CFD) analyses. Five Impeller SSM designs of different taper, release, and attack angles were studied. Compared to a standard SSM of the same size, the Impeller SSM demonstrated a pressure drop (and power) reduction up to 18.2%. Such reductions could lead to significant energy saving and size reduction in static mixer industrial applications. Experimental results also show the ability of AM to fabricate the custom Impeller SSM without using costly machining and joining techniques.

Numerical thermal augmentation of ternary nanofluid in a tube with stent, torus-ring and surface-grooved twisted tapes under non-uniform wall temperature

This paper presents a numerical analysis of flow and thermal characteristics in a plain tube with various inserts, including a stent, torus ring, and surface-grooved twisted tape, using a ternary nanofluid consisting of SiO2, ZnO, and CaO nanoparticles as the working fluid. Computational fluid dynamics simulations were conducted using ANSYS Fluent commercial codes, focusing on laminar Reynolds numbers ranging from 500 to 2000 and a non-uniform wall temperature profile. The objective is to investigate the Nusselt number, pressure drop, thermal performance, and pumping power of the ternary nanofluid with nanoparticle concentrations ranging from 0.01 to 0.05%, considering various geometrical parameters of the grooved twisted tape insert, such as thickness ratio (0.019–0.033), width ratio (0.38–0.68), and pitch ratio (1.77–5.77). The results show that flow and thermal indicators such as Nusselt number, thermal performance factor, pressure drop and pumping power increased with thickness and width ratios. Conversely, an increase in pitch ratio results in lower flow and thermal indicators. For instance, in a plane tube without inserts, no noticeable difference in pressure drop is observed and the thermal performance factor is about 1.87-1.25 times that of pure water when nanoparticle concentration is increased from 0.01 to 0.05%. The width ratio 0.68, thickness ratio 0.033 and pitch ratio 1.77 yielded a maximum thermal performance factor of about 1.4, 1.7 and 2.3 more than smooth tube, respectively, and a maximum pumping power 0.000654 W, 0.000223 W and 0.00020 W, respectively. The findings emphasize significant improvements in heat transfer and flow properties, shedding light on the innovative configuration's potential application as an improved heat exchanger. This research advances understanding of ternary nanofluid behavior and provides useful information for enhancing heat transfer in a variety of engineering applications.

Performance improvement of photovoltaic/thermal systems by using twisted tapes in the coolant tubes with different cross-section patterns

A numerical technique is applied to study the efficacy of integrating twisted tapes to the collector of Photovoltaic/Thermal (PV/T) units on the system performance when the tubes with different cross-sections are used. Hence, computational fluid dynamics is employed to evaluate PV/T systems with and without twisted tapes when using cylindrical, rectangular, and triangular patterns for the tube cross-section. The effect of employing twisted tapes with various pitch-to-width ratios (YD) of 3, 4 and 5 is evaluated. The impact of the total inlet mass flow rate ranging from 25 to 150 Lhr is also studied. To analyze the system performance the evaluation of energy and exergy is performed. The results demonstrated that the triangular pattern is the optimum pattern for the tube cross-section without twisted tapes. However, inserting a twisted tape makes the cylindrical tube superior to other designs from electrical and thermal aspects. A collector employing a cylindrical tube with and without a twisted tape could increase the module's electrical efficiency by 7.2 and 9%, respectively. Also, it was observed that integrating twisted tape with the lowest value of pitch-to-width ratio could decrease the surface temperature by 3.2 and 17.55 K compared to the systems with cylindrical tubes and PV alone.

Numerical Simulation Study on the Influence of Twist Tape Parameters on Hydrate Particle Deposition

Numerical simulation is used to carry out research on the swirl flow transportation of a hydrate in the pipeline under the condition of the whole rotation of the twist tape using DPM (discrete phase modeling) and RNG (renormalization group) k-ε. The influence of different twist tape parameters on the swirl number and concentration distribution of hydrate particles is analyzed. The structure parameters of the twist tape are optimized, based on the swirl efficiency evaluation parameters of a gas-solid two-phase pipeline. Finally, the twist tape is compared with different working conditions: the local rotation of twist tape and an ordinary pipeline. The results show that the areas of a high concentration of particles are near the twist tapes, and the concentration of particles on the leeward side of the twist tapes is higher than that on the windward side. The minimum concentration area at the axial position gradually increases with the increase of the flow distance, and the hydrate particles do not deposit at the bottom of the whole pipe section. The placement angle of the twist tape is greater, and the particle concentration area near the twist tape is also larger. The best placement angle is 25°. Under the condition of constant swirl strength, the range of the high particle concentration area will not increase indefinitely, and it is constant when the height of the twist tape is D/6 and the optimal height is D/6. There should not be too many twist tapes, as this will affect the carrying effect. The optimal number of twist tapes is three. The particle carrying distance of the local swirl flow generation is about double that of the ordinary pipe. The particle carrying distance of the four twist tape pipes is 3.5 times greater than that of the ordinary pipe. The particle carrying distance of the whole swirl flow generation is 6.6 times higher than that of the ordinary pipe. The particle carrying effect is 89% higher than that of the four twist tape pipes. The particle carrying effect is 230% higher than that of the local swirl flow generation. The particle carrying effect is 560% higher than that of the ordinary pipe.

Exploration of ARC-class reactor vessel and divertor cooling system

ARC (Affordable, Robust, and Compact) is a compact tokamak design proposed by Commonwealth Fusion Systems and the Plasma Science and Fusion Center at the Massachusetts Institute of Technology.ARC features REBCO (Rare Earth Barium Copper Oxide) high temperature superconducting magnets, demountable coils, a replaceable vacuum vessel and a liquid immersion blanket (LIB). The LIB is a Li2BeF4 (FLiBe) molten that provides cooling, tritium breeding, and neutron shielding. The compact dimensions of ARC result in very high heat fluxes on the first wall (0.4MW/m2) and the divertor (10MW/m2). These heat fluxes mandate a high heat transfer coefficient in the cooling channels that cannot be achieved without adopting heat transfer enhancement techniques. The scope of this work is to analyze the FLiBe flows through the vacuum vessel channels, and the exploration of different passive heat transfer enhancement techniques to provide adequate cooling to the vessel, which must withstand considerable heat flux and volumetric power generation. Minimum cooling requirements for vessel and divertor are evaluated, and the performance of different turbulence promoters is compared to find the most advantageous design. In particular, wire coil inserts decrease pressure drops by 39% with respect to twisted tapes inserts while providing the same cooling performance.

Optimization of thermohydraulic performance of tube heat exchanger with L twisted tape

A numerical investigation was conducted to explore the heat transfer optimization effect of circular tube heat exchanger with L-shaped twisted tape insert and to find the optimal parameter design in this paper. For better thermohydraulic performance, the effects of twist pitch (P), inner diameter (D), tape width (W) and number of tape (N) were studied with Reynolds number ranged from 1875 to 3750. Moreover, response surface method (RSM) was employed to indicate the relationship between the Nusselt number (Nu) and these parameters. With the analysis of flow structure inside the tube, it was conducted that the twisted tape insert was helpful to transform the axial velocity of fluid to radial velocity, forming vortex in the L region. The numerical results showed that the Nu and friction factor (f) of the tube fitted with L-shaped twisted tape insert gained an 199% to 208% increase and 674% to 696% when compared with that of smooth tube respectively. Besides, an optimal parameters set was obtained with P = 65.59 mm, W = 0.95 mm, D = 8.80 mm, in which the Nu and f were increased by 204% and 704% respectively as the results of response surface method.

Photovoltaic-thermal system combined with wavy tubes, twisted tape inserts and a novel coolant fluid: energy and exergy analysis

To create a highly efficient photovoltaic-thermal (PV-T) system and maximise the energy and exergy efficiency, this study aims to propose an innovative configuration of a PV-T system comprising wavy tubes with twisted-tape inserts. Following the validation of a numerical model, a parametric study has been conducted to assess the geometrical effects of twisted tape and wavy tubes, as well as the coolant fluid type and velocity, on the overall performance of a PV-T system, located in Shiraz, Iran. It is found that employing twisted tape improves the energy and exergy efficiency by approx. 6.3%. The best configuration yields 12.4% and 16.8% increase in energy and exergy efficiency compared to conventional PV systems. This is achieved at 15% volumetric concentration of microencapsulated phase change material slurry. The monthly variation of global horizontal irradiance in Shiraz highly affected the energy and exergy efficiency of PV-T, with July and October exhibiting the most efficient months, corresponding to 90% and 11.3%, respectively.

Impact of Nano Additives in Heat Exchangers with Twisted Tapes and Rings to Increase Efficiency: A Review

The heat exchanger is crucial to all systems and applications that use it. Researchers are primarily focused on improving this component’s thermal conductivity to improve its efficiency. This was achieved by using one or more of the following strategies: inserting tapes with various shapes and numbers, inserting rings of various shapes and spacing between each, and transforming a basic liquid into a nanoliquid by adding nanomaterials with high conductivity and ultra-small particle sizes. Different types of nanomaterials were added in varying concentrations. In earlier studies, it was found that every increase in heat transfer was accompanied by a pressure drop at both ends of the exchanger. The amount of heat transferred and the pressure drop are affected by many factors, such as the torsion tape ratio, the pitch of the ring, and whether the pitch faces the direction of flow or not. Heat transfer rates can also be impacted by factors such as the length and angle of the wings, how many rings and tapes there are, and whether the rings and tapes contain holes or wings. In addition, the Reynolds number, the type, conductivity, and size of nanomaterials, and the base fluid used in the nanofluid affect this. It is possible for the shape of the exchanger tube, as well as varying rates of rise, to introduce such impacts. In this study, the factors, costs, and benefits of using any technology to increase the efficiency of the heat exchanger are reviewed so that the user can make an informed decision about the technology to use.

Study of thermal performance of double pipe heat exchanger using W-cut twisted tape

ABSTRACT An experimental analysis was carried out to estimate Nusselt number and friction factor behavior in a double pipe heat exchanger for W-cut twisted tape, in which Reynolds numbers ranging from 5500 to 16,000 are used, and the depth of W-cut to width of twisted tape ratio are 0.2, 0.4, and 0.6 in twisted tape of 10 mm width and 1 mm thickness. Effects of twist ratio are also analyzed by varying twist ratio 5, 10 and 15. It has been found that using twisted tape inserts causes turbulence and flow separation, resulting in better fluid mixing. Due to augmentation in turbulence, an enhancement in heat transfer and TPF was observed. Validation of test section done with predefined correlation and experimental results. It has been found that peak enhancement in Nusselt number and friction factor observed at Reynolds number 5500 for depth of W-cut 6 mm and twist ratio of 5 is\\\\are 105.47% and 301% respectively. Maximum TPF and friction factor were seen under the same circumstances. For the current analysis, the maximum TPF observed is 1.35.

Experimental evaluation and thermal performance analysis of a twisted tape with dimple configuration in a heat exchanger

This contemporary experiment examines heat transfer and friction factor of liquid (water) going in a double pipe heat exchanger with twisted tape (TT) insert. Effect of twisted tape in DPHE inserts dimple configuration by providing a dimple protrusion surface only on the front face with a hole configuration placed adjacent to it over the tube length of 1500 mm and diverse dimple diameter (D) and dimple diameter-to-depth ratio (D/H) proceeding heat transfer and friction factor(f) characteristics are analysed in this work. Twist ratio for all cases is 5.5 for each twist, range of Reynolds number (Re) 6000–14,000, D of 2, 4, and 6 mm and (D/H) of 1.5, 3 and 4.5. Six twisted tapes with dimples were tested, and their performance was compared to that of twist with plain tube. It is discovered that the Nusselt number is the deviance with respect to Reynolds number of a plain tube (without twisted tape and dimples) with an inner tube diameter of d = 16 mm. It is evident from the plot that there is an increase in the rate of Nusselt number with a subsequent increase in the value of Reynolds number. Through experimental analysis conducted, Therefore, Optimum value for higher Nusselt number is standard for discussion at D/H = 3 for different diameter as it 111 (for Re = 13987) and 58 (for Re = 6180) using D = 4 mm. As a result of the investigation, it is determined that the depth and diameter of the dimple is directly proportional to the friction factor. Therefore, optimum value for lower friction factor is benchmarked for discussion at D/H = 4.5 for different diameter as it 0.1033 (for Re = 13987) and 0.1437 (for Re = 6180).

Study of Twisted Tape Inserts Segmental Application in Low-Concentrated Solar Parabolic Trough Collectors

This article presents the results of an analysis of heat enhancement intensification using twisted tapes in linear absorbers for low-concentration parabolic trough collectors, a technology frequently considered as a supplementary energy source for industrial heat production. This contribution proposes a segmented application of different twisted tapes to intensify heat absorption. A 33.7 mm tubular absorber placed in the collector focal point with an aperture of 1.8 m was selected. The temperature range of the heat transfer fluid was chosen at 60–250 °C. The impact of inserts with twisted ratios of 1, 2 and 4 on system operation was analysed using the Ansys Fluent and mathematical model. The models used were validated based on experimental results from a parabolic trough collector with solar simulator test bench. The results indicated that for the range of mass flow between 0.15–0.3 kg/s, the most optimal is applying twisted ratio 1, except for the highest-temperature section. In this section, it is more optimal to use an insert with a twisted ratio 2, due to the lower need for pumping and the higher efficiency increment. The long-term analysis for the case study plant indicated that the proposed approach increased power gain by 0.27%.

Heat transfer enhancement in a tube with a twisted tape inserted for various length ratios

ABSTRACT Energy efficiency is a major concern in pipe systems, particularly in applications where heat transfer is significant. Twisted tape insertion is used to enhance heat transfer in pipes. In this numerical study, twisted tapes with various length ratios (LR) (30–100%) were inserted into a tube filled with water. The tube surface was subjected to a uniform heat flux. The Nusselt number (Nu) and friction factor (f) variations were investigated for several Reynolds number values (Re) (2500–10,000) under hydrodynamically developed and thermally developing flow conditions between laminar and turbulent flows in the transition and low-turbulent regime. The results are validated with the available theoretical results and experiments. The maximum Nu enhancement is observed at an LR of 90% based on a factor of 1.55; an LR of 70% demonstrated a similar factor of ~1.5 and a friction factor 3.7 times more than that of plain tubes. This ratio provides the best results for the enhancement factor, which is 1.2 times higher at the maximum level. Consequently, an LR of 70% is considered to be sufficient to obtain an optimum combination of maximum heat transfer and minimum friction combination, and this combination is preferred over completely filling the tube with twisted tape.

Thermal and Flow Analysis of TiO2 Nanofluid Flow in Circular and Square Ducts with Multiple Twisted Tape Inserts

A numerical study is conducted to observe the thermal and flow performance of TiO2 nanofluid in the circular and square ducts with different twisted tape arrangements. The presence of the twisted tape in the tube induces swirl flow, which aids in the heat transfer, but at the penalty of a higher friction factor. The results also reveal that the maximum Nusselt number enhancement is obtained in the circular tube when the counter-triple twisted tape arrangement (C-TTs) is adopted while it is co-triple twisted tape arrangement (Co-TTs) for the case of square duct. Besides, the highest friction factor is observed for the Co-TTs for both circular and square ducts. The heat transfer and friction factor in the circular duct are greater than that of the square duct. The highest thermal performance factor of 1.286 is obtained when the single twisted tape and 1.5% nanofluid are used in the circular tube. However, multiple twisted tape inserts in the square duct contributes to improved thermal performance at a relatively lower friction factor when compared to the circular tube. Therefore, it is recommended to implement the square duct with multiple inserts for compact or microchannel heat exchanger for heat transfer application.

Performance evaluation of serpentine tube coupled with modified twisted tapes utilized as heat extraction coil in solar ponds

The thermal energy collected and stored by solar ponds is usually extracted by using some heat exchangers, where curved tubes form their core. The present study aims to appraise the performance of a serpentine tube under varied mass flow rates and inlet temperatures of the working fluid. Three different types of twisted tapes nominated as uniform twist pitches (U), low to high twist pitches (LH), and high to low twist pitches (HL) are employed to enhance the heat extraction rate. This article is the first report addressing the application of non-uniform twisted tapes as turbulators in a serpentine tube. In this regard, a solar pond simulator containing salt water is designed and fabricated. Numerical simulations are also carried out to display the transport phenomena inside the models. The numerical results are compared with the experimental data, and a close agreement is found. From the thermal point of view, the sequence of twisted tapes is LH > HL > U, while it follows the order of U > LH > HL according to the frictional loss. The findings demonstrate that depending on operating conditions, the heat extracted by the modified cases is 4 to 70% more than the base model. It is also found that employing non-uniform twisted tapes results in lower flow resistance compared to the uniform case. The pressure drop augmentations produced by U, LH, and HL TTs are 26.5%, 17.5%, and 10.4%. Further, the overall performance index is higher than unity for all the enhanced cases. The best case is the twisted tape having low to high twist pitches (LH) which has an average performance index from 2.03 to 2.71.

Heat transfer improvement of hybrid nanofluid with use of twisted tapes within a heat exchanger

Influence of utilizing porous zone on behavior of hybrid nanofluid through a duct was scrutinized by applying of FVM approach. Darcy model in three dimensional steady flow forms has been applied and related terms have been incorporated in momentum equations. Mixture of nanoparticles (MWCNT + Al2O3) and H2O creates hybrid nanofluids which were utilized as testing fluid. To improve the absorbing heat, helical tape was incorporated. The test section of duct is middle 40 cm of the duct where the porous zone and helical tapes were mounted. Validation base of previous published work and studying the grid leads to the most accurate outputs with lowest computing price. Impacts of Da, ϕ and Re on treatment of working fluid have been examined. Selecting greater amounts of ϕ and Re makes Nu intensify by 7.27% and 35.58%. As permeability of zone increases, fluid can moves faster along the axial direction and Nu declines about 6.78%.

Develop a New Correlation between Thermal Radiation and Heat Source in Dual-Tube Heat Exchanger with a Twist Ratio Insert and Dimple Configurations: An Experimental Study

The goal of this research is to convey an outlook of heat transfer and friction factor in an exper-imental study with a double-pipe heat exchanger (DPHE). In process heat transformation (HT) and friction factor(f) in a DPHE counter-flow with a twisted tape (TT) arrangement by dimple inserts. The grooves were a kind of concavity that enhanced thermal transfer while only slightly degrading pressure. Heat transmission (HT) and friction factor(f) were investigated employing dimples with twisting tape of varying diameters along with uniform diameter (D) to the diameter-to-depth ratio (D/H). The impact of using twisted tape with various dimpled diameters D = 2, 4, and 6 mm at a uniform (D/H) = 1.5, 3 and 4.5 on heat transmission and friction factor properties were discussed. The dimple diameter (D) was directly connected to the friction coefficient (f), hence the highest value of friction factor was established at (D) = 6 mm. Furthermore, the best performance of Nusselt number (Nu) and performance evaluation criteria (PEC) was determined at a diameter of 4 mm. As a result, dimpled twisted tape additions are an excellent and cost-effective approach to improve heat transformation in heat exchangers. With fluid as a water, lower parameters, and higher Reynolds number (Re) resulted in better thermal conditions. Thermal performance and friction factor(f) correlations were developed with regard to the ge-ometry of the dimple diameter (D), its ratio (D/H), ‘Re’, and a good correspondence with the experimental data was achieved. The novel geometry caused a smaller pressure drop despite its higher convection heat transfer coefficient. The results also showed that raising the ‘Re’ and nanofluid concentration, the pressure drop increased.

Thermohydraulic performance investigation of a heat exchanger with combined effect of ribbed insert and Therminol55/MXene+ Al2O3 nanofluid: A numerical two-phase approach

MXene-based nanofluids are novel trends with improved dispersion stability and thermophysical characteristics over previously established nanofluids. In the present work, the thermohydraulic characteristics of a double pipe heat exchanger (DPHEX) with a Therminol55(TH55)/MXene + Al2O3 nanofluid and various geometrically shaped (triangular, rectangular) ribbed twisted tape (TT) inserts are numerically investigated using the ANSYS Fluent interface. A counter flow arrangement with three different types of inserts (RRTT, TRTT, TT) and TH55/MXene + Al2O3 nanofluid at 0.20 wt% are studied inside the heat exchanger. Adding ribbed inserts to the conventional TT insert enhances the turbulence intensity by creating extra vortices. The thermal boundary layer grows thinner due to increased axial and radial velocity. Due to the substantial flow obstruction, adding ribs increases the overall pressure drop between the inlet and outlet. The maximum increase in Nu is 11.04 % using nanofluid instead of water, whereas the combination of insert and nanofluid exhibited up to 105 % enhancement for rectangular-ribbed TT compared to the plain tube. Nevertheless, the pressure decrease is found to be maximum in rectangular-ribbed TT because of significant flow disruption. This was likewise true with triangular-ribbed TT and TT insert. According to the PEC assessment, the RRTT insert had a maximum PEC value of 1.67 greater than TRTT and traditional TT for both TH55 and nanofluid flowing inside the tube. To summarize, the combination of TH55/MXene + Al2O3 RRTT insert may be a promising choice for improving heat exchanger performance in a new generation efficient thermal system.

Critical Current Analysis of a Three-Slot Cable by Using of YBCO Tapes

Stacking tapes is one of the methods to increase the transport current of a superconducting cable. A three-slot cable (TSC) by using twisted stacked YBCO tapes is presented in this article. The YBCO tapes embedded in the slot generate an axial strain. Excessive strain leads to a degradation of the critical current. The strain equation is used to obtain the critical twist pitch, which is verified by embedding the tapes into some formers with different twist pitches. For a cable with a diameter of 6 mm and a YBCO tape width of 3 mm, the calculated critical twist pitch is about to 86 mm, which is consistent with the experimental result. Since the magnetic field generated by the stacked tapes causes critical current degradation, the Kim model is used to investigate the critical current of the proposed TSC. Calculation results for different stacking thicknesses compared with experimental results, the maximum error is found to be about 6%. In this article, the critical current of TSC cable is investigated to provide data for future applications of twisting multiple TSC cables to make cable-in-conduit conductors for a high magnetic field and high-current scenarios.
