The basic objective of the current investigation by using CFD simulation is to select the appropriate material to fabricate Vortex tubes in meteorological conditions, which can improve efficiency and performance. The simulation results of vortex tubes were used in obtaining the performance for various materials such as copper, stainlessteel, brass, PVC, CPVC, acrylic, nylon, and bronze. The ratio of length of the hot tube and inner diameter was chosen as (L/D) 40 with the consistent inner diameter of the hot tube as 15 mm. Compressed air is passed through an inlet pipe between 2 and 12 bars in the step of 2 bars. 2D CFD was developed and analyzed with Ansys Fluent to access the performance of the vortex tube. Finally, after evaluating all simulation values for eight materials for performance depending upon their physical properties varies in the sequence from copper–bronze–brass–stainless steel–CPVC–PVC–acrylic–nylon material.
Rocket nozzle is part of a rocket in which the burnt propellant from the combustion chamber can exhaust through the nozzle to get the desire amount of thrust and required Mach number. The nozzle turns the static high pressure high temperature gas to low pressure, low temperature, and high velocity gases. To analyse this we have used CFD. Where CFD is the fluid mechanics which is integral part of the design, this is based on numerical methods and algorithm method. To analyse the fluid flow in supersonic rocket nozzle the CFD analysis software is used. Mainly in this work had focused on the pressure, temperature, velocity and Mach number of the mass flow in nozzle by changing the divergent angle. The oblique shock is a main conception and the presence of oblique shock which will create the instabilities. And it is visualized that the shock wave is creating in the nozzle at the 5° of divergent angle and it slowly started eliminating from the nozzle after 5° of divergent angle. To overcome this problem some of the trials are made for different divergent angle such as 5°, 10° 11°, 12°, 15°, and 20°. After 12o of divergent angle the flow parameters will start get reducing. At 20o the sudden drop of flow parameter will occur. By considering all the results at different divergent angle, the 11° angle is more efficient and found all the flow parameters such as velocity, temperature, pressure and Mach number of the mass flow are at required condition.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
