conjugate natural convection heat transfer in arotating enclosure

The aim of the present numerical study to analyze the conjugate natural convection heat transfer in arotating enclosure with finite wall thickness. the enclosure executes a steady counterclockwise an-gular velocity about its longitudinal axis. the staggered grid arrangement together with the markerand cell (mac) method was employed to solve the governing equations. the governing parametersconsidered are the wall thickness, 0:05 ≤ d ≤ 0:2, the conductivity ratio, 0:5 ≤ kr ≤ 10 and thetaylor number, 8:9 ×104 ≤ ta ≤ 1:1×10^6, and the centrifugal force is assumed weaker than thecoriolis force. it is found that decreasing the conductivity ratio or/and rotational speed stabilizeof the convective flow and heat transfer oscillation. the global quantity of the heat transfer rateincreases by increasing the conductivity ratio and it decreases about 12% by increasing 20% wallthickness for the considered rotational speeds.
