Mathematical Model of Unsaturated and Supersaturated Moist Air Flow Based on Two Passive Scalar Transport Equations

Original language description

The article deals with the development of two passive scalars based moist air flow model. The proposed model allows solving two-phase flow, where condensation or evaporation of water droplets occurs. The model is developed to by applicable in the limit of very low Mach number flow. The moist air is assumed to be in thermodynamics equilibrium and two phases are well mixed. It is the model of homogeneous equilibrium kind. The equation for the dry air mass fraction and the total enthalpy of moist air are solved together with overall continuity equation and with overall momentum equations. The model is solved by using ANSYS Fluent code. Mixing of supersaturated and unsaturated moist air streams is shown as an example. It has been shown that the model is able to predict temperature decrease of the supersaturated stream due to evaporation of liquid phase.
