Effects of Heat-Induced Pollutants due to Thermosolutal Exchanger in Ventilation System

Abstract

Fluid flow as well as heat and mass transfer due to a double diffusive mixed convection in air around a thermally and solutally activated square block inside a ventilated enclosure have been numerically simulated. The block is at higher temperature and concentration than those of the inlet fluid, which is at ambient temperature and concentration and is passed through various slots of the left vertical wall and flushed out at the right vertical wall. Both experimental and numerical confrontations build up in the positioning of the airflow source to establish disparity of the reduced effect on velocity and temperature distribution. The objective of the present study is to characterize the mixed air distribution system due to a heated or coolant exchanger in the core of the enclosure combined with the inlet cold fluid. Effective cooling and heat transfer performance is studied by changing the locations of the inlet and outlet port with the variation of Richardson number , which is practically applicable for building ventilation and cooling of equipment. It is found that the average temperature of the fluid has a maximum variation when the inlet and outlet ports are placed along the upper and lower parts of the enclosure with the increase of Richardson number.
