Hi All,
I am simulating a axial fan in SimpleFOAM. The solution is converged but the results are totally strange. I have noticed two problems. 1. The flow is happening in opposite direction the fan is pushing 2. The pressure and velocity magnitudes are very high. I have posted some pictures to give you an idea. The mechCheck is ok. I am using total pressure inlet and static pressure outet. The domain is simple, a cylinder with fan inside it. I suspect is fvSchemes issue. BTW, how to submit <code> in the forum? Code: FoamFile { version 2.0; class dictionary; format ascii; location "system"; object fvSchemes; } ddtSchemes { default steadyState; } gradSchemes { default Gauss linear; } divSchemes { default bounded Gauss upwind; div(phi,U) bounded Gauss upwind; div(phi,omega) bounded Gauss upwind; div(phi,k) bounded Gauss upwind; div(R) Gauss linear; div((nuEff*dev(T(grad(U))))) Gauss linear; } laplacianSchemes { default Gauss linear corrected; } interpolationSchemes { default linear; } snGradSchemes { default corrected; } fluxRequired { default no; p ; } |
