Thank you for your response.nI'm using the Eulerian model with evaporation/condensation model: thermal phase change with constant value of saturation temperature. The heat transfer coefficients are defined using the two resistance model with the Ranz Marshal correlation to estimate the Nusselt number of each phase.nCase S-2 and S-5 (which are both steady-state) have similar velocity vector diagram with more water-liquid volume fraction in the domain for Case S-5 compared to Case S-2.nHowever, for Case S-10 (transient case) the velocity becomes extremely high, I believe it doesn't converge.nPlease find the comparisonn of the three cases attached. Thank you.n
