Abstract

The heat addition by the phase transition of water vapor in humid air, which changes the properties of compressible flows around airfoils, is investigated by numerical simulations. The computations are based on a recent small-disturbance approach by Rusak and Lee [11]. This approach describes the heat release by the nonequi- librium and homogeneous condensation process using the classical nucleation and droplet growth models. The nonlinear interaction between the heat transfer by the condensation, the kinetic energy of the compressible flow, and the thermal proper- ties of the flow is explored and the similarity parameters which govern the problem are presented. The results of the calculations show good agreement with available simulations using the Euler equations. The similarit
