ashokbarik is on a distinguished road
i am using the RPI model to simulate the hot plate. The hot plate is applied with constant heat flux of 50000 w/m2. Water at temperature of 97 degree cenntrigrade is impeged on that plte. i am using Eulerian Multiphase model with RNG K-E model for turbulence to be generated during the bubble lift off. My simulation is conveying the real physics ,but it is producing the required amount of vapour, which it has to produce with same heat flux.
Would some one help me what to do if vapour fraction is not sufficent, with same heat flux.
