A master's thesis at the College of Engineering at the University of Basrah discussed a numerical study on the effect of rotation on mixed convection inside a channel with an open cavity containing a rotating cylinder.
The thesis presented by the student Iman Ghazi Muhammad dealt with solving equations numerically, including the continuity equation, momentum and energy using computational fluid dynamics.
A limited number of controlling volumes were used, the equations for mass, momentum and energy were solved and cases were studied for different angular velocities and different positions of the cylinder. The study criteria represented the performance of the effect of Reynolds number (150_50), Richardson number (10_0.1) and the angular velocity of the cylinder and the position of the cylinder for the hot wall.
The thesis aims at a numerical study of the effect of the angular velocity and the position of the cylinder on the process of heat transfer by mixed convection.
The thesis concluded that the buoyancy effect becomes negligible for small values of Ri in the range Ri>1. Nusselt number increases with Ri and as Reynolds values increase.
