• The processes of heat and mass transfer during cooling of heated sphere in the subcooled liquid are studied. When a heated solid surface is submerged in a liquid with a considerably lower saturation temperature, a vapor film can be formed around the heater. Using of non-equilibrium boundary conditions gives the possibility to solve this problem with taking into account peculiarities of the transport processes at the vapor-liquid interface. The Fourier thermal conductivity law is used for description of heat transport process in vapor film. The heat from external boundary of vapor film is removed through natural convection. Pressure balance is provided by hydrostatic pressure and non-equilibrium boundary condition. The obtained calculation results are compared with the previous calculation data and known experimental results.
