Hi friends
i want to solve a 3D isolated rotor of a compressor with "COODLES". i use fixedValue for velocity and zeroGradient for pressure in inlet. in the outlet extrapolatedOutlet boundary condition is used. i want to use "radial equilibrium equation" as a boundary condition for outlet but it seems that OpenFoam has not this boundary condition. i will be so thankfull for your help |

of my (third) attempt at an approximate radial equilibrium outflow boundary condition. I am also new to OpenFOAM (2 weeks), and I also dearly needed such a boundary condition. It is not perfect, you have to tune it a bit by playing with the input options, but for my application of interest (swirling flow in an annulus) it works quite well. If it suits your needs, let me know.
