Abstract
Now-a-days, the first and foremost important quality of any research or development is its eco-friendly nature. As we know environment safety has become an important aspect of the industries and people in common. Vortex tube is also known as non-conventional cooling device that will produce cold air and hot air when we passed compressed air from compressor without causing any harm to the nature. In vortex tube, when a compressed air from compressor is tangentially passed into vortex chamber a free and forced vortex flow will be generated which will be divide into two air streams i.e., one has lower temperature than inlet temperature and other one has higher temperature than inlet temperature. It can be used for any type of spot cooling application. In this research an attempt is made to fabricate and test a simple vortex tube. The effect of change in length and diameter of vortex tube i.e., (L/D) ratio is investigated and presented in this paper.
Highlights
General refrigeration systems use very harmful refrigerants, as they are the major cause for depleting ozone layer
Major research work is focussing on to eliminate the use of very harmful refrigerant but side by side we are focussing on their efficiency or c.o.p
The vortex tube is known as non-conventional cooling device which was invented by scientist named RANQUE so it is called as ranque tube, which is a remarkably a simple device, reliable and produces 2 air stream i.e., one has higher temperature than inlet temperature and other one has lower temperature than inlet temperature simultaneously from the compressed gas
Summary
General refrigeration systems use very harmful refrigerants, as they are the major cause for depleting ozone layer. Component of the air in the vortex tube reverses from the control valve and moves from the higher temperature end to the lower temperature end. 2 types of vortex flow is created in this chamber i.e., free and forced one and air travels in circular like motion along the circumference of hot side. When compressed air is passed to the vortex chamber it will produce a free vortex motion of air This air will flow toward the end of tube where we have a control valve in the shape of conical. We have designed 2 different vortex tube by taking different length for hot and cold side and different diameter of pipes so that we will get 2 length and diameter ratio i.e., L/D (Table 1)
