Numerical analysis of water, ethylene glycol and nanofluid based radiator using CFD

Abstract In this study performance evaluation of Radiator is numerically investigated with different fluids and different volume flow rates using CFD technique. Radiator 3D model is developed in SOLIDWORKS and same model is imported to ANSYS-FLUENT for further analysis. Mesh sensitivity analysis shows that 0.5 mm element size is optimum for the selected radiator model. For this study, various fluids such as pure water, water with 50% ethylene glycol, water with 0.05% concentration of Al2O3 nanoparticle, water with 0.1% concentration of Al2O3 nanoparticle and water with 0.2% concentration of Al2O3 nanoparticle are chosen as cooling fluid. Results show that, the Nusselt Number increases with the volume of rate and particle concentration. Also, the heat transfer coefficient increases with the particle concentration and volume of rate. The performance of the Nanofluid based radiator is enhanced by 10.64% and 3.82% in terms of Nusselt Number and heat transfer coefficient respectively when compared with pure water. Finally, water and ethylene glycol mixture with Al2O3 nanoparticle 0.05% concentration has better performance than remaining fluids.

Hydrodynamic analysis of different impellers used in the stir casting process

In this work, the hydrodynamic behavior of four types of impellers used in the manufacture of metal matrix composites (MMC) through the stir casting process is analyzed, in order to determine which of them is adequate to generate a uniform flow in the metal. Liquid and thereby achieve a uniform distribution of reinforcing particles. The impellers analyzed are the belt type, the vane type, the propeller type and the turbine type. As a first part, the parameters of each one of them were determined to later carry out the modeling in SolidWorks. Some properties of liquid aluminum were also determined, such as density and viscosity for a melting temperature. These characteristics were assigned in the software used. As results, the flow velocities and turbulences that occur with each impeller were obtained, being the propeller-type impeller the one that shows a more uniform distribution in terms of velocities.

Study of driving dynamics of modular forestry tillage machine-tractor units in CAE SolidWorks Motion

The issues of simulation studies driving dynamics of wheeled forestry machine-tractor units on the surface with obstacles are considered. The method of simulation modeling in CAD SolidWorks and CAE SolidWorks Motion is used. A simplified 3d-model of the MTZ-82.1 agricultural wheeled tractor was created, preserving all the main geometric and mass-inertia parameters of the moving elements. The tractor model was equipped with front and rear mounted modular forest tillage implements in the transport position. The research was performed on a virtual track with four different types of obstacles similar to those found in forest conditions. In a computer experiment, three different schemes of units were studied and the following parameters were obtained: wheel lift height, lateral displacement of the center of gravity, and linear speed fluctuations. Analysis of the results showed that the 0+1 scheme (rear-mounted single-row harrow) was the most stable. The heaviest scheme 1+2 (front-mounted drum chopper and rear-mounted two-row harrow) also had satisfactory stability. The least stable was a tractor equipped according to the 0+2 scheme (rear-mounted two-row harrow). The virtual experiment allowed us to study the dynamic stability of various forestry units in the transport position and establish the most stable configurations.

RETRACTED ARTICLE: On the design of racing car suspension

The suspension assembly of a vehicle is a vital component in its ability to function safely and effectively. This paper details the design and simulation of the James Cook University Motorsports 2nd generation vehicle for the Formula Society of Automotive Engineers competition. After in-depth research it was decided that a pull-rod suspension system would be the most effective assembly for the Gen 2 car. Contrary to the current push-rod suspension on the Gen 1 car, the pull-rods allow the centre of gravity to be lowered, which is ideal. Working closely with the rear drive train, cockpit and upright teams, a design was conceived and developed. After several redesigns a final model was able to be created. SolidWorks was the tool used to generate the components created in the design phase. This is an extremely powerful program that allows the user to not only produce a three-dimensional component but also allow future modifications to be made to the component to change its dimensions. It was decided this was a vitally important ability, as future modifications will be needed when less conservative loading cases are discovered and then applied. The SolidWorks models where then transported to a computational simulation program, ANSYS. ANSYS, like SolidWorks, was an important tool in verifying design assumptions and concepts. With this program loading cases where able to be applied to the system to understand how they would react and if they would fail under the stresses applied.

DEVELOPMENT OF QUICK RETURN MECHANISM FOR EXPERIMENTATION USING SOLIDWORKS

Quick Return Mechanisms (QRMs) are one of the essential accessories used in machine tools which involve reciprocating cutting action with a quick return stroke and a constant angular velocity of driving crank. The aim of this work was to simulate, design and construct a prototype of a QRM that can be used for demonstration and instrumentation. The QRM was simulated using Solidworks and a prototype was developed from the simulated results. The experiment was conducted using the prototype. The kinematic simulation of the Solidworks model was compared with the kinematics of motion of the prototype. The result showed that the Percentage Stroke Length error was 0.36%. It was observed that, there was no significant difference in the simulated and experimental results, hence, the prototype can be used for demonstration and experimentation to assist students in understanding basic principles of the machine operation.

A novel modular deployable mechanism for the truss antenna: Assembly principle and performance analysis

The truss antenna based on the tetrahedral deployable mechanism has the advantages of good deployment stability, high stiffness, large folding rate and high profile accuracy. A new modular deployable antenna mechanism based on the 3RR-3URU tetrahedral symmetrical combination unit is proposed in the present study. It should be indicated that the construction method of the modular mechanism is proposed initially based on the 3RR-3URU tetrahedral symmetrical combination unit as a basic module. The assembly method of modular mechanism and the arrangement of the joints connecting different modules are introduced in detail. Moreover, the large aperture antenna mechanism composed of more modules is described. The basic module and the modular mechanism composed of multiple modules belong to the spatial multi-closed-loop mechanism, so the degree of freedom (DOF) of the one-circle modular mechanism is analyzed by using the idea of ‘equivalent mechanism’ and screw theory. Moreover, the law of DOF of the multi-circle modular mechanism is further explored. The screw topological graph and screw coefficient matrix are applied for this kind of multi-closed-loop mechanism to obtain the results of the reasonable choice of actuation. Then, kinematics analysis of the modular mechanism is completed by the coordinate transformation and vector method. The folding rate is discussed and compared with other mechanisms for the truss antenna based on the kinematics. Finally, the simulation analysis model is established by using Solidworks and Adams modeling and simulation software. The correctness of the DOF and kinematics theory analysis is verified by the simulation analysis. Furthermore, the proposed mechanism is compared with the existing mechanisms. The proposed modular deployable antenna mechanism has the advantages of large folding rate and high reconfigurability. Therefore, it obtains great application prospects in the fields of the aerospace deployable antennas.

MODELING OF THE FRAME STRENGTH OF THE MISSILE AND BOMBING GEAR OF THE Мi-8МСБ-В HELICOPTER IN THE TEST PROCESS

The problem of ensuring the frame strength of missile and bombing gear of the Ми-8МСБ-В helicopter pylon in the course of testing is considered. The methods of calculation of the frame strength at maximum load are developed to solve this problem; as well as modeling of design for the main operating modes of the helicopter is conducted.
 Previously, on the basis of force factors the loading coefficients of the helicopter on its operational modes are determined, particularly in combat use (dive with a volley of missiles and bombing).
 While conducting modeling the advanced methods of calculating the design of the frame strength parameters were applied, i.e. the analytical manual calculation and computational programs of computer-aided design (CAD). Manually calculating the forces and stresses in the framework (using cut nodes) the frame was idealized as rod model with hinged connections of the elements in the nodes A system of equations for each node was formed, which were solved in MathCAD. In the automated calculation of forces and stresses in the design of the frame the finite element method was implemented, which is used in WinMachine programs and SolidWorks Modeling.
 The mathematical modeling of the frame was made at the maximum anticipated in-flight loads for determination the critical force and the maximum stress in the construction elements. In addition, the analysis for the redundant deformation was carried out.
 Performed calculations, mathematical and simulation modelling proved that the necessary strength requirements are met for all the elements of the frame under its maximum load in all flight operational modes.

Anatomical modelling and simplified modelling in total hip replacement: difference in contact mechanics perspective

Total hip replacements (THR) is a surgical operation to replace defect bone at the hip joints. The rate of succession of THR post-operative still debatable as complication and failure rate of the prosthesis still exists. Edge-loading, dislocation, fracture and longevity are among the concerned issues with many studies were conducted via software analysis. This study aims to simulate the difference of anatomical and simplified modelling in finite element analysis (FEA) and investigate edge-loading effect at different inclination angle in both modelling conditions. A CT scan hemi-pelvic model was reshaped and converted into 3D model in SolidWorks and the next step, FEA was conducted in ANSYS Workbench V16 at different inclination angle. Anatomical and simplified model were run in ANSYS Workbench and the results were recorded. The anatomical modelling produced less contact pressure range 26% to 51% compared with simplified modelling at four inclination angle conditions. Von Mises stress and total deformation in anatomical also produced reduction of more than 65%. Both modelling conditions shows agreement that elevated inclination angle had induced higher contact pressure at superior region of acetabular cup. The inclusion of hemi-pelvic model gives lower value recorded in FEA as contact stress dispersed into the bone that already integrated with the implant given statistically significant (p<0.05). Noteworthy to include bone integration into implant during FEA study to produce unambiguous contact mechanics studies.

Manufacturing of personalized prosthetic leg using solid modeling and 3d printing

After surgical amputation, the availability of a prosthetic device with correct dimensional measurements for the amputee limb is a general problem faced by several patients annually due to varying body sizes and dimensions of every individual. The prosthetic leg is generally manufactured in preferred sizes through machining of materials giving rise to several problems like long time taken to manufacture; unavailability of prosthetic leg to cater specific individual dimension, large geographic/regional distances having prosthetics and lack of infrastructure to manufacture such a device within a short period with high accuracy and dimensions. etc. This paper introduces a novel technique of an alternative approach for the development of prosthetic limbs on a Solid-works Model and then 3-D printing of the prostheses and casting it afterwards that allows the design of prostheses with required body dimensions of the individual, within a short span of time and with high accuracy.

Simulation of temperature field of basin insulator and optimization of oven structure

Due to the 'filler' effect, the pot insulators need to be solidified from bottom to top during the curing process, which requires the epoxy to have a reasonable temperature gradient during curing. To improve the curing quality of the basin insulator in the oven, this study uses the SolidWorks modeling software to establish the physical model and simulates the whole process of the curing process of the ultra high voltage (UHV) basin insulator by computer simulation technology and the finite element principle. For the case in which the temperature difference between the concave side and the convex side of the section of the basin insulator is too large during the curing process, the existing oven structure is improved, and the temperature difference between the concave side and the convex side of the front and rear basin insulator sections is compared. The simulation results show that the optimized oven structure has a better temperature field distribution of the basin insulator during the curing process. The correctness of the simulation was verified by testing the temperature and strain during the curing process of the basin insulator. Compared with the old oven, the new oven structure reduces strain on the insulator during curing by about 10%, indicating the superiority of the new oven. © 2019 Institute of Electrical Engineers of Japan.

Моделювання процесу охолодження картонного полотна

Effective cooling of a cardboard web affects its technical and technological characteristics and metal intensity of the refrigeration part. The modern designs of refrigeration parts and cylinders are examined and the most optimal design of the refrigeration cylinder is selected. Conducting heat exchange processes in the technology of production of pulp and paper products upon receipt of cardboard is one of the most progressive approaches. The refrigeration part of the cardboard machine plays an important role in the technology of obtaining high quality cardboard products. The cooling of the cardboard web allows it to be sufficiently soft and elastic and suitable for calendaring, as well as to prevent electrification of dry cardboard during friction. As a refrigerant, the authors propose to use cold water, which is a fairly cheap coolant. The standard design of the refrigeration cylinder assumes that the refrigerant is fed into the middle of the refrigeration cylinder and distributed around the periphery of the inner surface, and the spent refrigerant is extracted from the sides of the cylinder. To increase the speed of the process of cooling the cardboard web, the authors proposed to install air sprays over the contact area of the web and the surface of the cooling cylinder. This will further cool the outer surface of the web that is not in contact with the surface of the cylinder, as well as create additional pressure of the web to the shell surface of the cylinder. 3D model of refrigerating part of cardboard machine was created. The simulation of the process of cooling the cardboard web using the SolidWorks modeling system was carried out and the temperature change along the thickness of the web was determined. The optimal temperature regimes of the process of cooling the web are determined and the dependence of the cardboard temperature change on its thickness is obtained.

Analysis of the Capabilities of Pistons Design using SOLIDWORKS models

The difficulty in designing internal combustion piston is determined by complex operating conditions. Piston is the busiest engine part. Combined mechanical and thermal loads work on it. Profiling the piston in two mutually perpendicular planes is a major part of its design. The shape of the piston in a cold state is quite different from the cylindrical one. The aim is, despite the varying amount of material in the various zones, when the working temperature reaches the piston to take cylindrical form, thus providing minimal clearance to the engine cylinder. Because it is a moving part, the parameters at work are hard to determine. There are studies of the piston temperature state, some of which are described and analysed.

Engineering Design of a Mechanical Decladder for Spent Nuclear Rod-Cuts

A practical scale mechanical decladder that can slit spent nuclear fuel rod-cuts (hulls + pellets) of several tens of kg HM/batch is being developed to supply UO2 pellets to a voloxidation process. The mechanical decladder is an apparatus for separating and recovering fuel material and cladding tubes by horizontally slitting the cladding tube of a fuel rod and a defective irradiated fuel rod. In this study, we address the engineering design of the mechanical decladder for the pretesting of rod-cut slitting. To obtain the requirements of the mechanical decladder, we first manufactured a slitter for testing based on the decladding and shearing conditions of hulls and pellets. The performance test of the testing device for decladding was carried out using a 2-CUT blade module and a 3-CUT blade module. We evaluated the decladding methods for the mechanical decladder and selected the 3-CUT blade module based on the results. A buckling measurement instrument was used to perform a buckling verification test according to the length of a rod-cut and to determine decladder dimensions. The optimum decladding rod-cut length for buckling prevention was calculated. Furthermore, we analyzed the decladding mechanism for various slitting methods. Design/fabrication and preliminary tests of the practical scale mechanical decladder were also performed. For this purpose, we constructed the main mechanism by utilizing the SolidWorks modeling and analysis program and fabricated a new mechanical decladder. Based on the derived requirements, a mechanical decladder with three main modules was designed and fabricated for testing. Simulated rod-cuts of zircaloy were also manufactured to test the basic performance of the decladder, and a data acquisition system was constructed using RSC 232 to measure decladding force and velocity. In the basic test, the rod-cut was completely sectioned into three evenly spaced locations by the new mechanical decladder.

Modelling and simulation of high density polyethylene liner installation in engineered landfill for optimum performance

Geomembrane liner is an important part of a landfill system that must be selected and installed properly to avoid high induced stresses and imperfections. Considering a fixed HDPE liner thickness of 2mm and variable masses in this study, the liner was modelled and simulated for 27 scenarios using Solidworks and Artificial Neural Networking approach. Static analysis was further performed on the Solidworks model under a distributed load of 4000kg in properly aligned and improperly aligned conditions to the base and side walls of a landfill system. The minimum stress and width of imperfection obtained from the Solidworks simulation was 77MPa and 34mm while 65MPa and 67mm was obtained from the ANN simulation. The liner failed outrageously in the improperly aligned condition with maximum induced stress of 3,606.521MPa, but no sign of failure was observed for the properly aligned condition which the maximum stress (0.018Mpa) was quite low. This investigation can serve as a guide towards proper installation of geomembrane liners for optimum performance in landfill applications.Keywords: Solid waste, engineered landfill, Geomembrane liner, Installation

Analysis of Shrinkage Compensation Factor (SCF) of FDM uPrint SE for Accuracy Enhancement

This paper scrutinizes the shrinkage of a component manufactured using Additive Manufacturing (AM) and emphasizes mainly on the change in dimensions of an AM component after printing. The physical model can be easily manufactured by having the CAD data in STL format for real time AM. However, deviation of product size in CAD model transforming to physical model will be existing due to the deformation of the material mainly because of shrinkage. So here an analysis is carried out to find the optimal shrinkage compensation factor (SCF) of the part manufactured by Fusion Deposition Modelling (FDM) machine which uses ABS P430 as the base raw material. To achieve the latter a suitable model part is considered taking all the dimension and geometrical constraints which are essential for finding SCF and through regression analysis with the help of Co-ordinate Measuring Machine (CMM) and Solid Works modeling, SCF is calculated. Based on the experimental study, dimensional accuracy of the part significantly improved after applying the SCF value of 0.068% which is assumed to be constant in all directions.

Investigation and Analysis of Static and Dynamic Behaviour of a New Natural Composite Material of a Wind Turbine Blade Using the Finite Element Method

A wind turbine blades modeling study is so critical because of their design, as we all know, domestic wind turbine blades are usually designed using aluminum alloy and glass fiber. In this paper we are going to study the resistance of a new natural composite material based on hemp fiber and an Epoxy matrix, for that we had conceived a three-dimensional model of the blade using aerodynamic profile parameters and geometric parameters on SolidWorks modeling software. Then, the model was imported into the ANSYS Workbench to perform a static, modal and harmonic analysis using FEM. The results were compared between the three materials; this comparative study shows that there is a good agreement between the three materials under stress. And for natural frequencies, the hemp fiber composite blade has higher natural frequencies than the aluminum alloy blade and the glass composite blade with a large standard deviation. For harmonic response, results show that the blade operates stably under resonance conditions, resonance does not occur and the composite hemp fiber blade functions safely
