| 内容記述 | The film condnsation in a laminar boundary layer flow is analyzed for the case of combined body force with forced convection. Introduction of the starting length parameter X_c enables us to formulate the problem without any specification for a flow model that film formation initiates at a certain point downstream of the leading edge; a non-wetted initial section exists over 0≦x<X_c. With the assumed various lengths of initial non-wetted region the boundary layer equations for a steam-air mixture have actually been computed by means of the finite difference schemes, for a wide variety of flow parameters : the uniform flow velocity, the mass fraction of steam and the bulk-to-wall temperature difference. The effect of initial non-wetted length on the heat transfer is examined. The results for the limiting case X_c→0 are estimated by extrapolation of the solutions for finite X_c's, and these are compared with the previous studies for the cases of mixed convection, and also the limiting case of body force only. | |||||||
