Vortex tube generates hot and cold streams from the compressed air, without any moving part or chemical reaction. In this paper, the performance of a vortex tube is first determined experimentally, for an L/D ratio of 5, and is simulated in CFD package. CFD analysis is then carried out for various L/D ratios (8, 9 and 10) of vortex tube, and the te...

... tube generally consists of chamber, nozzle, diaphragm, valve, hot air side and cold air side, as shown in the figure (Figure 1). There is no other part inside the chamber; the fluid dynamic or thermodynamic effects, therefore, makes the temperature difference. ...

A vortex tube is a compact energy device which splits a compressed air stream into hot and cold streams at opposite ends. This paper presents an insight on Ranque-Hilsch Vortex Tube (RHVT) with divergent nozzle, stream of compressed air to swirl in swirl chamber, conical projection and a diaphragm. The principle of vortex tube is used in vortex air...

Waste heat recovery unit becoming a mandatory and integral part of modern day heat interacting devices, through regeneration waste heat energy is recovered within the plant which increases the overall thermal efficiency. In the present work investigation is made on one such heat recovery system, where we used the interaction of solid gas in cyclone separators connecting tube. The experimental setup of 60mm diameter and 3m height was used and made with iron. The effect of flow parameters like feed rate, velocity and the geometrical features like height, and particle size variations were studied, and found that the heat transfer rate and thermal effectiveness increases with velocity and reduces further, hence optimum velocity needs to be maintained for maximum effectiveness since the thermal effectiveness variation of solid and air is opposite to each other.
