Free convection heat transfer through coupled thermal boundary layers in a partitioned triangular enclosure
Saha, Suvash C., Gu, YuanTong, & Hossain, Md. Anwar (2011) Free convection heat transfer through coupled thermal boundary layers in a partitioned triangular enclosure. In Proceedings of the International Conference on Mechanical Engineering 2011, Department of Mechanical Engineering, Bangladesh University of Engineering and Technology, Dhaka, Bangladesh.
A numerical investigation has been carried out for the coupled thermal boundary layers on both sides of a partition placed in an isosceles triangular enclosure along its middle symmetric line. The working fluid is considered as air which is initially quiescent. A sudden temperature difference between two zones of the enclosure has been imposed to trigger the natural convection. It is anticipated from the numerical simulations that the coupled thermal boundary layers development adjacent to the partition undergoes three distinct stages; namely an initial stage, a transitional stage and a steady state stage. Time dependent features of the coupled thermal boundary layers as well as the overall natural convection flow in the partitioned enclosure have been discussed and compared with the non-partitioned enclosure. Moreover, heat transfer as a form of local and overall average Nusselt number through the coupled thermal boundary layers and the inclined walls is also examined. The details results will be discussed in the full paper.
