Mixer Module Updates

For users of the Mixer Module, COMSOL Multiphysics® version 6.3 introduces new Rotating Machinery, High Mach Number Flow interfaces for all transport-equation eddy-viscosity models and a new Mixing Plane feature for the High Mach Number Flow interfaces. This feature performs circumferential averaging of flow quantities while accounting for the direction of characteristics. The mixing plane approach is an efficient method for modeling sectors of centrifugal pumps, turbines, and compressors. The new predefined study Frozen Rotor with Initialization automatically adds a Mixing Plane Initialization study step, which computes average flow quantities using the initial values.
