As engineers routinely applying CFD to a wide range of turbomachinery and aerospace
applications, we often face technical judgments as to the applicability of certain numerical
approaches or physical models used in a simulation. One such judgment for rotating
machinery relates to the choice of either applying a time accurate transient moving mesh
approach or a simplified steady-state multiple rotating frames (MRF) approach. This modeling
decision can be critical especially when simulating the flow through rotating systems which
contain a low blade count.
