Values of k & epsilon in the moving wall
Dear Friends! I ask you some questions about imposing the k & epsilon in the moving wall. I have calculated the unshrouded centrifugal type turbomachinery. I used the relative velocity, rotating coordinate, standard k-epsilon turbulence modeling. In imposing the wall B.C, stationary part( e.g shroud casing, vainless diffuser) will have the circumferential velocity (-omega * vec r). And I treated in these parts as walls in order to use wall function. How do I impose the value of k & epsilon values. Would you like to give me an answer. Thank you for reading.
