Abstract
The aim of this study is to investigate the design parameter effects of an aspirating cooling system on the outer surface temperature of a household pyrolytic oven glass. Pyrolytic ovens include complicated components, such as an oven door, a cross-flow fan and an aspirating cooling system, and their complex interactions should be investigated in detail. In this study, the oven door and cross flow fan and aspirating cooling systems were modeled as a three dimensional system using a computational fluid dynamics and heat transfer method to investigate the fluid flow and temperature distribution of outer surface of the oven door. The simulation model predicted the temperature distribution based on the cross flow fan speed, cross flow fan position and channel design of the aspirating cooling system. The numerical results were validated against results obtained from an experimental study. The computational results show that the rotational speed of the cross flow fan, the cross flow fan position and the channel design of the aspirating cooling system play important roles in affecting the outer surface temperature distribution of the oven glass of a pyrolytic oven.
