Numerical Simulation of Iced Wing Using Separating Shear Layer Fixed Turbulence Models

Aerodynamic prediction of glaze-ice accretion on airfoils and wings is studied using the Reynolds-averaged Navier–Stokes method. Two separation fixed turbulence models are developed by considering nonequilibrium characteristics turbulence. The key ad hoc fix a term local ratio turbulent production to dissipation, which used amplify destruction equation increase eddy viscosity in separating shear layer fully region. A stress limiter adopted appropriately simulate beginning process transition when under development. proposed terms can be easily implemented into current solvers. case flat-plate, periodic hill, two iced three-dimensional swept wing with ice accretions numerically tested modified models. results indicate that fixes improve ability predicting stall behavior at large angles attack. simulated averaged flowfield intensity distribution consistent experimental data.
