Vortex tube is a device which is capable of separating hot and cold gas stream from an inlet gas stream with a proper pressure .Separating cold and hot streams by using vortex tube can be used in industrial applications such as cooling equipment and refrigerators. This device suits for vital applications because of its light weight, simple and more importantly it is compact. Many researchers have carried out research to identify the factors which affects Vortex tube performance. This paper aims to study the effect of geometrical parameters on vortex tube made of two types of homogeneous wood to check the performance by using compressed air as a working fluid .The data was presented till date of the experimental work carried out by researchers for optimum performance of a vortex tube parameters such as the length of VT to its inlet diameter (L/ D) ratio, use of different material in developing the vortex tube and its effect are discussed in detail.

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.
