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.
