A Numerical Study on Temperature Distribution on Ceiling for Different Locations and Sizes of the Outflow Opening

유출개구부의 위치와 크기에 따른 천장의 온도분포에 관한 수치연구

The finite volume method was utilized for computation of convection heat transfer in a two-dimensional enclosure with an inflow opening and an outflow opening. The objective of this study is to investigate temperature distribution on ceiling for different locations and sizes of the outflow opening. The inflow opening was set to be H$_{i}$=0 and U=50. The results fur different sizes of the opening H$_{0}$=0.1, 0.2, 0.3, and 0.4 shooed similar flow patterns and temperature distribution. Location of the outflow opening, however, influenced significantly on the temperature distribution on the ceiling.ing.
