A RARE HEAT TRANSFER PHENOMENON IN AN INCLINED WATER CAVITY DEPENDING ON THE WARM PLATE TEMPERATURES

This paper is concerned with the three-dimensional and twodimensional heat transfer in an inclined water layer with deg of the cavity angle that is calculated numerically by the PHOENICS Code. The thickness of the water is 2.5 cm , and the length and depth both are 25 cm . The warm plate generates heat per unit time and volume to set the mean temperature of its warm plate , and the temperature of the cold plate is fixed at considering the melting of ice. The Nusselt number ratio of is similar to that of the vertical cavity angle in the previous study. Moreover, the is considered in small angles of and 30 deg. As the results, the indicates less than 1.39 in the range of so that can be approximately estimated by which is calculated easily. However, 3D calculation is necessary to estimate correctly in the range of .
