Convective heat transfer in ventilated space with various partitions

The laminar convective heat transfer in ventilated space with various horizontal partitions was studied numerically and experimentally. For the numerical study, the governing equations were solved by using a finite volume method for various numbers Re, Gr, Pr and partition numbers. The experimental study was conducted by using a holographic interferometer. The isotherms and velocity vectors have been presented for various parameters. As the number and length of partition increased, convective heat transfer decreased. Based on the numerical data, correlation equations were obtained for the mean Nusselt number in term of Gr/Re-2. In the region of Gr/Re-2 less than or equal to 1, the mean Nusselt number was small, but in the region of Gr/Re-2 > 1, the mean Nusselt number was constant.
