Abstract
This study examines the influence of a rotating cylinder on heat transmitted by mixed convection in an air-filled square space. The appropriate mathematical models for continuous, incompressible, 2-dimensional, laminar flows with Boussinseq’s approach are solved numerically, where constant fluid properties have been used. The most important parameters examined are the speed of rotation (w = 0 - 1000) and the angle of inclination (Ɵ = 0 - 90o), the study has been carried out with the Reynolds number (Re = 104), the Prandtl number (Pr = 0.7). The objective of this study is to find the changes of the mean Nusselt number according to tilt angle, where it has been concluded that the mean. Nusselt number according to increasing tilt angle will increase until the angle reaches 45o, after that its value begins to decrease. It has been noticed that the highest values of the Nusselt number are reached for an angle of inclination close to 45°. The mean Nusselt number has been concluded to increase 162.19% as a tilt angle increased from 0° to 45°. Moreover, the mean Nusselt number increased by 264.6% as the angles of rotation increased from 0 to 1000 rad / s at an angle of 45°. A good agreement has been achieved by comparing the results of this work with other previous work.
