CFD Analysis on Nozzle Inclinations in Forced Air Cooling System for Industries

Abstract

Forced air cooling systems are cost-effective and environmentally sustainable solutions to cooling because they use less energy. The forced air coolers performance is directly related to the nozzles ability at given humidity. Cool air is blown in to the room. However, system may not deliver cool air in the monsoon season as humidity level in the atmospheric air is already high and then further adding moisture to the room air increases discomfort level. Small converging nozzles are placed in the panel. As air passes through nozzles, temperature drops. Thus, no need to spray water to the panel to cool air. In this research, a new attempt has been made to find the theoretical feasibility of using converging nozzles in forced air cooling system which is used to cool the room. In this research, ANSYS FLUENT has been used with different converging angles. Comparing the nozzle performance with various angles suggested a suitable atmosphere for optimum system temperature drop.
