Multi-objective optimization of a composite phase change material-based heat sink under non-uniform discrete heating

This paper presents a novel heat sink that integrates paraffin/copper foam composite phase change material. The heat sink base is subject to non-uniform heating with multiple discrete heat sources on a circuit board. Numerical simulations are performed using FLUENT software to investigate its thermal transfer characteristics and performance. Three types of paraffin, including RT35HC, RT44HC, and RT54HC, are compared. An optimization scheme that combines Artificial Neural Network and Non-Dominated Sorting Genetic Algorithm-II is proposed to (a) maximize the operation time and (b) minimize the heat sink mass. Operation time is defined as the time for simulated chips to reach set point temperature, 80 °C. The result shows that local overheating caused by non-uniform heating limits operation time. The optimization method shows great robustness and effectiveness. Three sets of non-dominated solutions are obtained, and optimal configurations are determined with further analysis. A figure of merit is defined as the ratio of charging time to heat sink mass. Optimal configuration's figure of merit increases by 1.2–44.0% comparing to original designs.

Performance analysis of nanoparticles-enhanced PCM: An experimental approach

In this paper, an experimental analysis of organic PCM is conducted. It includes an experimental study of paraffin type organic phase change material while suggesting a way to improve the low thermal conductivity, a feature that is the main disadvantage of especially organic phase change materials. In particular, temperature profiles of PCM for different hot source temperatures are examined, while determining the heat stored in the material and the speed at which the melting front moves under the assumption of uniform movement of the melt interface and solid material. Subsequently, and in order to increase the conductivity of the PCM and thus the rate of evolution, copper and aluminum oxide nanoparticles powder are added and the hybrid PCM is compared in terms of temperature profiles and storage capacity with the pure PCM. The presence of 0.165% Cu nanoparticles reduces the thermal charge duration by 25.3% while the presence of Cu-Al2O3 hybrid nanoparticles at a concentration of 0.165% −0.816% reduces the duration by 10.8%.

Modelling the conditions for natural convection onset in open-cell porous Al/paraffin composite phase change materials: Effects of temperature, paraffin type and metallic structure geometry

Composite Phase Change Materials (PCMs) can be made combining a PCM, i.e., a material that is able store/release heat by its melting/solidification, and a low-amount of well distributed high-melting and high-thermal conductivity phase with the aim of improving the overall conductivity of the material and keeping its high heat storage capability. The composite made by a paraffin and a porous structure of aluminium (Al) has been considered as the representative of this material class. The design of these materials should not only take into account the melting temperature (Tm) and the volume fraction of the paraffin, but also the geometrical distribution and coarseness of the Al phase, which relate to the effective thermal conductivity of the composite as well as the occurrence of natural convection once the PCM is in the molten state. In the present paper, the inverse Body Centred Cubic (BCC) structure has been confirmed to be the most suitable to model high porosity Al foams. For their BCC modelled structure, an analytical equation is proposed for the evaluation of the overall thermal conductivity of the composite PCMs. Also, new best fit equations for predicting permeability of BBC structure are proposed. Analytical description is also given for the Rayleigh-Darcy number obtained as a product of material-dependent term (related to Tm and volume fraction of PCM) and the geometry dependent term (related to volume fraction of PCM, permeability as well as to material coarseness alternatively given in terms of pores per inch, pore size or unit cell length). The model has been validated by means of literature available experimental data. The proposed simplified model can further be adjusted to correlate the onset of natural convection through the local temperature gradient for the composite PCMs.

Pathological analysis of batch safety testing of veterinary vaccines using small laboratory animals.

Batch safety tests (BSTs) of veterinary vaccines are conducted using small laboratory animals to assure the safety of vaccines according to several criteria, including clinical signs and change in body weight. Although the latter is used as an evaluation index in BSTs, there have been no reports on the internal changes that affect body weight during the test period. Therefore, we analyzed BST via pathological examination of the tested animals. Here, BSTs were performed for 176 batches using mice and 126 batches using of guinea pigs. Most of the gross findings could be classified into four lesion types (nodules, adhesions, ascites, no apparent signs), with only one vaccine inducing lesions that could not be classified into any of these four types. Histopathological examination revealed that the reactions caused by BST were pyogenic and/or granulomatous inflammation. Nodular or adhesive lesions comprised more severe pyogenic granulomatous inflammation than ascites or cases with no apparent gross lesions. These nodular or adhesive lesions were more frequently induced by vaccines that contained an adjuvant than by vaccines that did not contain an adjuvant. The cases with “exceptional” gross findings histologically presented severe necrosis of the hematopoietic system. Additional testing showed that these “exceptional” lesions were induced when a specific type of light liquid paraffin was injected along with other vaccine additives. Our results show that body weight loss and/or lesions during BST were induced by proinflammatory properties of the tested vaccines and that BST is a sensitive method for detecting unexpected effects of vaccine components.

The Economic Impact of Paraffin Type and Substrate Mixture on the Production of Grafted Vines—Case Study Muscat Ottonel

The study focussed on a nursery by analyzing its strategic choices to obtain the best profit on grapevine planting material. The production of grapevine grafts involves high labor and material costs. In this study, Muscat Ottonel grape variety grafted on Oppenheim Sellection 4 rootstock was paraffined with different types of wax: standard wax (SW), paraffin with 8-chinolinol (8C) and paraffin with oxiquinolein (OX) (before callusing), and silver color (S), blue color (B) and standard (SW) paraffin (after grafting callusing and before planting in field nursery). After uprooting from the field nursery, all variants were paraffined with red paraffin for storage. The unit cost price was calculated based on total expenses and the yield of grafts obtained in the vine field nursery. The lowest price per unit cost was recorded for the 8C/S variant, directly related to the first quality yield after uprooting from the nursery. The highest profit rate was for the 8C/S variant, while the lowest was registered to the SW/SW variant. The grafts of the 8C/S variant were potted in three rooting mixtures. Variant B (forest ground 60% + black peat 25% + river sand 10% + conifer sawdust 5%) generated the highest yield of the potted grafted vine with a rate of profit of over 170%, due to the lower production cost and high yield of potted vines, while variant C (forest ground 70% + river sand 15% + conifer sawdust 15%), determinate the lowest yield. Results may be useful in orienting the small-to-medium grapevine planting materials producers to choose the best cooperative strategies, which nurseries might implement to enhance their competitiveness and survive in the long-run.

Thermal storage properties of lightweight concrete incorporating phase change materials with different fusion points in hybrid form for high temperature applications

In this study, the thermal storage properties of lightweight concrete incorporating two types of phase change materials (PCM) with two different fusion points were investigated. Two types of PCM, polyethylene glycol (PEG) and paraffin (PRF), were impregnated into porous aggregates using high temperatures. The PCM aggregates were mixed with concrete at different proportions of PEG/PRF aggregates from 0/100 to 100/0 with 25% intervals. The experimental series consisted of thermal property tests (such as thermal conductivity, specific heat, and latent heat), and some basic properties (such as compressive strength, density, water absorption, and abrasion resistance). The results showed that incorporating PCM aggregates into lightweight concrete helped increase the workability, lower the moisture absorption, and increase the mechanical properties. For thermal properties, both thermal conductivity (k) and specific heat were found to depend strongly on the state of PCM. The latent heat of lightweight concrete with PCM aggregates in hybrid form were found to be higher than that of single type PCM aggregates.

HOW TO OPTIMIZE CULTURE MEDIA OSMOLALITY IN IVF TREATMENTS

Study aim was compare osmolality in sequential and single step culture media, covered with two types of oil mineral and paraffin, in two types of incubators, dry and humid. A prospective observational study was performed from March to November 2019. For each incubator, humid water jacket (Forma 4130, Thermo Scientific) and dry bench top (G185, K-Systems), both trigas, a total of 30 dishes were prepared with sequential (Cleavage Medium, Cook) and single step media (CSCM, Irvine Scientific), covered with paraffin oil (Ovoil, Vitrolife). Another 30 dishes were prepared as mentioned above, covered with mineral oil (Light Mineral Oil, Irvine Scientific). Statistical analysis was performed using ANOVA. Twenty 35x10 millimeters dishes (Falcon), at a time, were prepared in a laminar flow hood at room temperature, using 25 microliter droplets of CSCM and Cleavage Medium. Ten were covered with 3,0 mL mineral oil and ten with paraffin oil. Half of the dishes were incubated in a dry incubator and another half in a humid. Osmolality (mOsm/kg) was measured using osmometer (Advanced Instruments) on day 1, 3, 5 and 7, one drop per day. Humid incubator is better for maintaining the osmolality of culture media, regardless of the type of oil used. CSCM has lowest levels of osmolality on day 1 when compared to Cleavage (263 X 286, p<0.0001) and maintained statistically lowest levels of osmolality on day 3, 5 and 7. In humid incubator, both culture media using paraffin or mineral oil, had similar osmolality on day 3 (269 X 270, P=0.391 for CSCM; 293 X 292, P=0.759 for Cleavage) , day 5 (270 X 271 P=0.978 for CSCM; 292 X 293 P=0.914 for Cleavage) and day 7 (271 X 271 P=0.999 for CSCM; 294 X 292 P=0.624 for Cleavage). Paraffin oil provided greater protection against evaporation, maintaining lower levels of osmolality, in a dry incubator, for CSCM media in D3 (281 x 284, P<0.001), D5 (287 x 293, P<0.001) e D7 (298 x 304, P<0.001). No significant difference was observed for Cleavage osmolality on day 3 and 5 (304 X 306, P=0.213) (314 X 314, P=1.0) comparing two types of oil, in a dry incubator. On day 7 paraffin oil is better to maintain osmolality (322 X 325, P=0.003). Our study demonstrated that combination of humid incubator and paraffin oil are better for maintaining osmolality level of single step media, which can improve continuous and undisturbed embryonic culture. Comparing humid versus dry benchtop incubators, using different types of oils and culture media, is necessary for better IVF results.

Nucleation promoting effect of fat shell on phase change material particles dispersed in an emulsion for thermal energy storage medium

Abstract Phase change material emulsions (PCMEs) can be prepared in which a paraffin type phase change material (PCM) is dispersed as small particles in water by the action of a surfactant. Using the latent heat of PCM particles in the PCME, the PCME can be used as an efficient heat storage and transport medium. PCM particles in the PCME are stabilized by the action of a surfactant, but they irreversibly coalesce over time. When the PCM particles change from liquid to solid, they can also show large supercooling because of their small size. These problems must be overcome for PCMEs to be used as efficient thermal media. In this study, PCM particles are emulsified with a high-melting-point fat containing a hydrophobic group consisting of single bonds, in an attempt to overcome these problems. The high-melting-point fat exists as fat shell around PCM. The stability and supercooling characteristics of the PCM particles are investigated. The amount of fat affects the stability of the emulsion. Adding 1.0–5.0 wt% fat is the optimum amount for stabilizing the emulsion. The fat promotes the nucleation of the PCM particles, and the degree of supercooling is suppressed to 3.0 K. Furthermore, the latent heat retained by the emulsion emulsified with fat is about 10% larger than the value obtained by multiplying the latent heat of the PCM by the content of the PCM. These features indicate that PCME prepared with high-melting point fat is suitable as high performance thermal energy storage medium for thermal energy storage and transport system.

CFD MODELING OF HEAT TRANSFER AND HYDRODYNAMICS PROCESSES IN A HEAT STORAGE TANK

Background. Today, heat storage tanks are an integral part of heating systems. However, modern designs of capacitive storage tanks are characterized by the phenomenon of thermocline and high thermal inertia. To minimize the aforementioned disadvantages, it is proposed to use a “thermal core”, for the formation of which it is necessary to select a substance with a high value of heat capacity.Objective. The purpose of the presented study is to simulate the process of heat and mass transfer in a storage tank with a “thermal core”, in the form of the binary tube located on the central axis, the inter tube space of which is filled with paraffin (a mixture of saturated hydrocarbons with melting point – from 45 °C to 65 °C; dense – 0.880–0.915 g/cm3 at 15 °C).Methods. Fluent software determines the temperature distribution in the heat storage tank under free convection conditions. The resulting data were then converted into a calculation module of the Transient Thermal software complex ANSYS, where further calculations of the non-stationary temperature distribution of the “thermal core” were carried out.Results. It is determined that the heat storage tank with a capacity of 1400 liters, heated for one hour by a heat transfer agent with a temperature of 115 °C, is cooled to 50 °C in 4 hours. The analysis of the hydrodynamic structure of the flow based on the distribution of the trajectories of movement of free-convective flows in the water column of the storage tank indicates the need to improve the design of the tank. It is determined that the use of the “thermal core”, regardless of the type of paraffin used for its formation, helps to reduce the stratification of temperature by tank height. The type of paraffin used to form the “heat core” has no significant effect on the cooling time of the heat storage tank as a whole. However, when using “ceresin” as a filler for the “heat core”, the average tank temperature is generally about 0.5 °C higher than for other paraffin types studied. Thus, it is “ceresin” that should be used as a “thermal core”.Conclusions. The result of the calculation of the inhomogeneous temperature field of all elements of the heat storage tank was used to determine the time of its complete cooling. The conducted research allows automating the process of calculation of the storage tanks as well as carrying out their modernization to increase the efficiency of use.

Choice of the Effective Solvent to Remove Paraffin Deposits in Conditions of Abnormally Low Reservoir Temperatures

The results of research on dissolution kinetics of petroleum paraffins and asphaltene-resin-paraffin deposits (ARPD) of the paraffin type in aliphatic, aliphatic-aromatic, and aliphatic-naphthenic-aromatic systems within the temperature range from 10 to 60° C have been discussed. The half-life periods, order of reactions, dissolution rate constants and activiation energy of destruction of paraffins and ARPD have been calculated. Differential scanning calorimetry has been used to study the phase transitions of petroleum and commercial paraffins in aliphatic and mixed hydrocarbon solvents. Based on the conducted research, recommendations for selection of an effective solvent to remove paraffin deposits at low temperatures of reservoirs have been proposed.

The temperature ranges of between 42-106 °C and 38–99 °C respectively were observed at the storage medium and absorber plate respectively with an average egg hatchability of 62.37% using the hybrid solar powered poultry egg incubator.

Feasibility of next-generation sequencing in clinical practice: results of a pilot study in the Department of Precision Medicine at the University of Campania ‘Luigi Vanvitelli’

BackgroundThe emerging role of next-generation sequencing (NGS) targeted panels is revolutionising our approach to cancer patients, providing information on gene alterations helpful for diagnosis and clinical decision, in a short time and with acceptable costs.Materials and methodsIn this work, we evaluated the clinical application of FoundationOne CDx test, a hybrid capture-based NGS. This test identifies alterations in 324 genes, tumour mutational burden and genomic signatures as microsatellite instability. The decision to obtain the NGS assay for a particular patient was done according to investigator’s choice.ResultsOverall, 122 tumour specimens were analysed, of which 84 (68.85%) succeeded. The success rate was influenced by type of specimen formalin-fixed paraffin embedded (FFPE block vs FFPE slides), by origin of the sample (surgery vs biopsy) and by time of fixation (<5 years vs ≥5 years). The most frequent subgroups of effective reports derived from colorectal cancer (25 samples), non-small-cell lung cancer (16 samples), ovarian cancer (10 samples), biliary tract cancer (9 samples), breast cancer (7 samples), gastric cancer (7 samples). The most frequent alterations found in whole population referred to TP53 (45.9%), KRAS (19.6%) and APC (13.9%). Furthermore, we performed an analysis of patients in whom this comprehensive genomic profiling (CGP) had a relevance for the patient’s disease.ConclusionsOn our opinion, CGP could be proposed in clinical practice in order to select patients that could most benefit from the analysis proposed, like patients with good performance status without any available treatments or with unexpected resistance to a therapy.

Analysis of the main parameters of crude oil pipeline transport

The paper presents results of experimental research and simulation of the main parameters of crude oil pipeline transport. In Serbia, 70 % of the produced oil belongs to a paraffin type, of which over 25 % has a high content of paraffin. High-content paraffin oil usually has a high pour point. The paraffin content in crude oil from Vojvodina, Serbia, is in the range 7.5 to 26 %, and the oil pour temperature varies from 18 to 36?C. The imported crude oil has a flow point max. 8?C. Homogenization, i.e. mixing of domestic and imported crude oil, improves the transport properties and decreases the pour point. After homogenization, the crude oil is pre-heated, and then transported by a pipeline to the refinery for further processing. Heating induces modification of crude oil physical properties, especially flow properties so to prevent wax formation within the oil pipeline. The aim of this paper was to determine operating parameters and flow characteristics for a particular oil pipeline (428 mm inner diameter, 91,000 m length) under real operating conditions. By heating in the range of 20 - 50?C, the viscosity of crude oil was reduced, approaching the viscosity of water. The pipeline is isolated (100 mm thick isolation) and buried into in the ground (1 m depth). It is found that the heat transfer coefficient has a dominant influence on the cooling rate of the oil in the pipeline. The heat transfer coefficient is mainly determined by the isolation thickness so that it was determined as 0.60 W m-2 K-1 for + 100 mm thickness, while it was 2.20 W m-2 K-1 for the non-isolated pipeline. Heat losses through the main pipeline ranged from 36 - 110 kJ m-1 h-1 (10 - 30 W m-1). The difference between the starting and the ending temperature of crude oil ranged from 10 to 12?C. Such a decrease of ?t = 10 oC and, consequently, the increase in viscosity induced a noti-ceable increase in the pressure drop and pump power by 3 to 4 %, at the maximum flowrate of 0.194 m3 s-1 (700 m3 h-1). The cooling rate during transportation under stationary thermal and hydraulic conditions is in the range 0.52 ? 0.5 oC h-1. In the case of domestic oil (Vojvodina, Serbia) transport, the downtime should not exceed 24 h, since stopping and cooling of the oil would result in formation of solid paraffin particles followed by oil gelation.

Thermal and sound properties of concrete mixed with high porous aggregates from manufacturing waste impregnated with phase change material

In this study, the properties of lightweight concrete manufactured from high porous aggregates impregnated with phase change material (PCM) were investigated. The aggregates used are in the form of waste retrieved from the manufacturing process of autoclaved aerated concrete block (ACC). The PCM (paraffin type) was used to impregnate the blocks at about 65% by weight. The non-PCM aggregates were replaced by PCM aggregates from 25 to 100% by volume. Five experiments were carried out: density and absorption (ASTM C138), compressive strength (EN12390), flexural strength (ASTM C78), thermal behavior, and sound transmission loss. Results showed increasing trends in density, compressive, and flexural strength with the increase PCM aggregate content. Thermal behavior is also found to improve with increasing PCM aggregates. Sound transmission loss, however, was found to decrease with increasing PCM aggregates.

Predicting asphaltene precipitation during titration of diluted crude oil with paraffin using artificial neural network (ANN)

Asphaltene precipitation from crude oil in underground reservoirs and on ground facilities is one of the major problems in a large portion of oil production units around the world. Many scaling equations and intelligent predictive models using the artificial neural network (ANN) are proposed in the literature but none of them can be applied when crude oil is diluted with any types of paraffin. In this study, feed forward artificial neural network is used for prediction of the amount of asphaltene precipitated weight percent of diluted crude oil with paraffin based on titration tests data from published literature. Trial and error method is utilized to optimize the artificial neural network topology in order to enhance its strength of generalization. The results showed that there is good agreement between experimental and predicted values. This predictive model can be applied to estimate the amount of asphaltene precipitated weight percent when the crude oil is diluted with paraffin and to avoid experimental measurement that is time-consuming and requires expensive experimental apparatus as well as complicated interpretation procedure.

Size Effect of Graphene Nanoparticles on the Thermal Properties of the Doped Phase Change Materials

In this study, the size effects of the Graphene nanoparticles (GNP) doped into a paraffin type organic phase change material (PCM) on thermal properties were examined. The thermal conductivities, melting/solidification temperatures and melting/solidification latent heats of the GNP/PCM composites, which were obtained by incorporating GNP nanoparticles with three different sizes into an organic PCM in mass fractions of 1%, 3% and 5%, were measured. The changes obtained in thermal properties were determined by referring to the non-doped PCM data. The results obtained showed that in low PCM mass fractions, thermal conductivity enhancement was a function of both surface area and thickness of the GNP nanoparticles. In addition, it was determined that thicker nanoparticles formed a more efficient conduction network at high PCM fractions. The reflections of the enhancements obtained in thermal conductivity on thermal performance were also determined in the study. Enhancements in thermal conductivity depending on the increase in thickness of GNP were obtained as 6.3%, 107.5% and 113.7% for 5% GNP(1-5nm)/ PCM, 5% GNP(6-8nm)/PCM and 5% GNP(11-15nm)/PCM composites, respectively. These thermal conductivity enhancements resulted performance increase in the energy storage unit around 5.5%, 18.3% and 20% respectively.

Nanoscopic Imaging of Human Tissue Sections via Physical and Isotropic Expansion.

In modern pathology, optical microscopy plays an important role in disease diagnosis by revealing microscopic structures of clinical specimens. However, the fundamental physical diffraction limit prevents interrogation of nanoscale anatomy and subtle pathological changes when using conventional optical imaging approaches. Here, we describe a simple and inexpensive protocol, called expansion pathology (ExPath), for nanoscale optical imaging of common types of clinical primary tissue specimens, including both fixed-frozen or formalin-fixed paraffin embedded (FFPE) tissue sections. This method circumvents the optical diffraction limit by chemically transforming the tissue samples into tissue-hydrogel hybrid and physically expanding them isotropically across multiple scales in pure water. Due to expansion, previously unresolvable molecules are separated and thus can be observed using a conventional optical microscope.

Interlayer structure and magnetic field-induced orientation of modified nanoclays in polymer aqueous solution

Structural changes and orientation of organically modified montmorillonite (Mt) were investigated by employing synchrotron small-angle X-ray scattering. Mt was modified with various cationic compound [3-(methacryloylamino)propyl]-trimethyl ammonium chloride (MPTC) contents (1.5, 3, 6, 12, and 18 CEC (cation exchange capacity) per 1 CEC of Mt). There are two types of modified Mt structures, lateral monolayer and paraffin type monolayer, in accordance with the MPTC contents. A paraffin-type monolayer is more dominant than a lateral monolayer for efficient packing of MPTC between Mt layers as the MPTC contents increase. In 10 wt% of the modified Mt series oriented in 1 M of polyacrylamide aqueous solution using a magnetic field (1.2 Tesla), the modified Mt series oriented parallel to the magnetic field within 200 s.

INVESTIGATION OF PETROLEUM FORM NEW WELLS OF EASTERN GEORGIA

&#x0D; &#x0D; &#x0D; &#x0D; Investigation of new wells of Satskhenisi oil (#7, #11, #12, #13, #14) and Manavi oil (#11, #12) was carried out. By IR spectroscopy it was established that Satskhenisi oil belonged to naphtheno-aromatic type and Manavi oil – to paraffinic type of oils. According to distribution of trace elements V, Fe, Ni, Co, Mo, Cu, Pb, Sn, Zn, Sr, Ba, Ti and the ratio V/Ni &lt;1, these oils refer to tertiary types of oils, which is explained by conditions of accumulation and geochemical transformation of the original organic compounds.Using simulation chromatographic distillation of Manavi oil from the #12 well were obtained naphtha and diesel fractions. In naphtha by method of gas-liquid chromatography were identified individual paraffinic, naphthenic and aromatic hydrocarbons and in diesel fraction – individual n-paraffinic hydrocarbons.By low content of sulfur, tar-asphaltene compounds and high yield of light fractions, Satskhensi and Manavi crude oils are high-quality raw material for production of commercial oil products for energy purposes.&#x0D; &#x0D; &#x0D; &#x0D;

Robust spin coating deposition process for paraffin phase-change films

In this work, for the first time, a cost-effective and resource-light spin coating process for the fabrication of the paraffin films on silicon and glass substrates is reported. Paraffin or alkane is a mechanical phase-change material (PCM) that undergoes approximately 15% reversible volumetric change through its solid-liquid transition. In addition, it is a low-loss dielectric with a loss tangent of 6 × 10−4 at 100 GHz which is a critical feature for certain radio frequency (RF) tunable devices. Traditionally physical vapor deposition techniques are used for paraffin PCM films. Here, an innovative and alternative process using spin coating is developed that overcomes the challenges imposed by the phase-change properties of the material. Spin coating of two types of paraffin—eicosane and hexatriacontane—on silicon, Pyrex and gold-coated substrates are studied. P-xylene is chosen as the solvent due to the solubility of eicosane and hexatriacontane at temperatures lower than its melting point. Effect of spin speed, spin time, substrate temperature, solution concentration, and substrate type on roughness and thickness of paraffin films are reported. Developed process offers a fast, repeatable, and resource-light deposition technique for hexatriacontane which can be utilized in developing several classes of new devices including low-loss RF architectures.
