Compressible fluid in converging-diverging nozzle has been studied for a long time. Although, shock waves and the dynamics of reactive compressible flow also have been investigated, the knowledge of heat transfer and flow characteristics of mist flow including phase change is lacking. In this study, the flow and phase change characteristics are investigated by focusing on the effects of radius and velocity of droplet, pressure of gas at inlet and outlet, and transport phenomena caused by differences of velocity and temperature between gas and liquid. In order to execute quasi-one dimensional numerical simulations, two-fluid model is employed, and fluid dynamic and thermodynamic amounts such as velocity and pressure distributions toward downstream of nozzle are calculated.
