چکیده انگلیسی
Practical flow problems with condensation due to phase change from water vapor to water liquid are numerically investigated. Fundamental equations solved in this study consist of conservation laws of mixed gas, water vapor, water liquid, and the number density of water droplets, coupled with the momentum equations and the energy equation. The classical condensation theory is employed for modeling homogeneous nucleation and nonequilibrium condensation. Heterogeneous nucleation is approximately modeled by assuming a constant radius and a constant number density of droplets. These equations are solved by a high-order high-resolution finite-difference method. As external flows, condensate transonic flows around NACA0012 airfoil in atmospheric flow conditions are calculated, and as internal flows, steady and unsteady transonic wet-steam flows through a steam turbine cascade channel are also calculated.
