HYDRODYNAMICS AND HEAT TRANSFER DURING THE FLOW OF A CONDENSATE FILM ALONG A VERTICAL SURFACE

The article considers the problem of hydrodynamics and heat exchange of a laminarly flowing condensate film over a vertical heat-removing surface during condensation of stationary steam. In this case, the velocity and temperature fields are determined under boundary conditions on the heat-removing surface and on the outer boundary of the condensate film. Obtained equations are used for calculation the thickness of a laminarly flowing film under the action of gravitational forces and the heat transfer coefficient during condensation of stationary steam
