NATURAL-CONVECTION IN INCLINED ENCLOSURES WITH MULTIPLE CONDUCTING PARTITIONS

Laminar natural convection and conduction in inclined enclosures havin g multiple partitions with finite thickness and conductivity have been studied theoretically. The governing equations are solved using finit e difference formulation and a volume control method. The study covers the range of Ra from 10(3) to 10(7), Phi from 0 to 180 deg, A = H/W f rom 1 to 20, B = w/W from 0.1 to 0.9, C = l/W from 0.01 to 0.1, and th e thermal conductivity ratio of partition to fluid k(r) from 1 to 10(4 ). The partition number N was varied from 1 to 5, The Prandtl number w as 0.72 (for air), The results are reduced in terms of Nu as a functio n of Ra, k(r), Phi, and various geometrical parameters (A, B, C), The streamlines and isotherms are produced to visualize the flow and tempe rature fields.
