| description | The aim of the present numerical study to analyze the conjugate natural convection heat transfer in a
rotating 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 Marker
and Cell (MAC) method was employed to solve the governing equations. The governing parameters
considered are the wall thickness, 0:05 D 0:2, the conductivity ratio, 0:5 Kr 10 and the
Taylor number, 8:9104 Ta 1:1106, and the centrifugal force is assumed weaker than the
Coriolis force. It is found that decreasing the conductivity ratio or/and rotational speed stabilize
of the convective flow and heat transfer oscillation. The global quantity of the heat transfer rate
increases by increasing the conductivity ratio and it decreases about 12% by increasing 20% wall
thickness for the considered rotational speeds. |
