This paper is concerned with the three-dimensional and two-dimensional heat transfer in an inclined water layer with  of the cavity angle that is calculated numerically by the PHOENICS Code. The thickness of the water is 2.5cm, and the length and depth both are 25cm. 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 30deg. 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
