Comparative and Analysis of Propeller Flow Field by Euler/NS Numerical Solutions

The propeller flows at different advance ratios are numerically simulated.The computations predict the rotational flow by solving Euler and NS equations respectively,using finite volume method and multi block,point-to-point grids.The comparison and analysis show that the numerical results,both the inviscid and viscous ones,go well with experimental results.Since the Euler results satisfy the accuracy demand in engineering already,the Euler solver is choose to more applicable to meet the time efficient in design period.
