STUDY ON CONVECTION HEAT TRANSFER IN A VENTILATED ROOM WITH HORIZONTAL PARTITIONS
Abstrakt
The turbulent convection heat transfer in a ventilated room with the horizontal partitions is studied numerically and experimentally. For the numerical study, the governing equations are solved by using a finite difference method for 50≤Re≤2000,1460≤Gr≤11585, Pr=0.71 and number of partition. The experimental study is investigated for the comparison of numerical results by using a holographic interferometer. The isotherms and velocity vectors have been represented for various parameters. As the number and length of partition increase, the convection heat transfer decreases. Based on the numerical data, a correlation equation is obtained for the dimensionless mean Nusselt number in term of Gr/Re2.
