An Analysis of Saturated Pool Film Boiling Heat Transfer around a Vertical Finite-Length Cylinder with a Convex Conical Bottom

The film boiling heat transfer around a vertical finite-length cylinder to saturated liquid was analyzed by taking into account each convective heat transfer on the three surfaces (bottom, side and top) of isothermal cylinder. The bottom is convex and conical. The vapor-liquid interface for the conical bottom surface and vertical lateral surface of the cylinder are assumed to be smooth. The connection condition of the vapor film between the conical bottom and the vertical lateral surface is given by the continuity of vapor flow rate around the lower end of the vertical lateral surface. The analytical result was compared with that of the vertical finite-length cylinder with a convex hemispherical bottom
