Abstract: |
Boundary layer flow with adverse pressure gradients (APG) is a basic problem in many engineering applications.Due to APG,the flow becomes complex and is difficult to be simulated by numerical method.In the present paper,a numerical study of two-dimensional boundary layer flow with APG is conducted based on Reynolds-averaged Navier-Stokes(RANS) equations.Six representative turbulence models are evaluated for APG flow.By comparison of numerical local frictional resistance coefficient and experimental results,it revealed that k-ω model has a high precision.Meanwhile,the turbulent kinetic energy is also studied,which may be helpful to study the APG flow's behavior. |
