The relationship for calculation of the onset of boiling depending on the saturation temperature (pressure) and the heat-flux density has been obtained. This was used as the basis for evaluating the impact of nonuniformity of a nonstationary heat flux on the temperature field of the evaporator. %8 2007-10-17
