• The purpose of this paper is to confirm the validity of the numerical model proposed in our previous paper for a two-dimensional analysis. The model can be applied to a wide range of temperatures from superfluid helium to normal fluid helium at vapor state. Two-dimensional numerical analysis for the horizontal channel with the heated bottom was performed, and the results were compared with experimental results. For low heat flux, the temperature profiles at steady state obtained from the analysis showed quantitative agreements with those from the experiment. For higher heat flux, the numerical results were able to represent the experimental temperature profiles qualitatively. In the transient analysis, the model was able to simulate the change of the velocity field caused by the phase transition. It was concluded that the validity of the proposed model in the temperature range including the phase transition was partially verified.
