Abstract

Due to the increase of energy cost, natural heat resources and industrial waste heat have been considered as potential energy resources and has been the centre of attraction among many researchers in recent years. Limitations of the use of these freely available energy resources arise primarily from the engineering cost/efficiency challenges. Some researchers have focused on improving the efficiency of existing techniques to utilize these energy resources. Some other researchers have focused on finding new techniques of extracting energy from these heat resources. The ratio of the cost/efficiency index can be reduced not only by increasing the efficiency, but also by reducing the engineering cost. This research deals with an innovative low-cost technique to produce swirling flow by industrial wasted hot air which is already in use to induce fire-whirl by burning fuel in the laboratory. The configuration consists of two identical half cylinders which are placed off-centre. Previous studies show such a simple configuration is able to induce a swirling flow within the chamber when a hot air inlet is used instead of a fire. In this computational work, a configuration with nearly arbitrary geometries is modelled and the effect of the inlet temperature and velocity on the swirling strength is assessed. The computational results show reasonable agreement with the existing experimental data.
