I have performed subcooled flow boiling simulations of water in an annulus with :<\/p>\n

    \n
  1. saturation temperature fixed based on outlet pressure conditions<\/li>\n
  2. saturation temperature as a function of pressure (i.e. by considering piece-wise linear variation). <\/li>\n<\/ol>\n

    The results obtained with saturation temperature as constant was matching with experimental results whereas with the function of pressure is not predicting good results i.e.deviation is more wrt experimental results i.e. it is over predicting radial vapor fraction values considerably. <\/p>\n

    Why is it so? I am using the thermal-phase change model for interfacial mass transfer. Is that model meant to fix the saturation temperature as fixed?<\/p>\n
