Abstract
The flow and thermal behavior of the phase change material in a novel geometry, namely, quadrantal cavity, is investigated numerically. The influences of curved wall temperatures of 32, 37, and 42 °C, the initial sub-cooling temperatures of 5, 10, and 15 °C which are lower than ambient temperature, are examined previously. Inclination angles for the range from 0 to 360° on flow and thermal performances are carefully studied. It is found that the inclination angles affects dramatically not only the time of complete thermal energy storage but also convection currents. The best performance is obtained for an inclination angle of 225°.
