Mixer Module Updates
For users of the Mixer Module, COMSOL Multiphysics® version 5.2a brings updated parts in the Parts Library and an updated version of the Mixer app that demonstrates the new part features. Review the Mixer Module updates in more detail below.
Updated Parts in the Mixer Module Parts Library
The axial, radial, and c-shaped impellers have been updated to include internal fluid-fluid control surfaces enclosing the impeller blades and hub. These can be used for calculations of the axial and radial flow numbers. The inclusion of upper, lower, and side control surfaces is enabled with a single Boolean parameter in the part.
Updated App: Mixer
The Mixer app has been updated with a plot of the shear rate and evaluations of the radial and axial flow numbers for each impeller.

Mixer_Module/Applications/mixerThe new shear-rate plot in the Mixer app allows for the design of mixing and is especially useful for processes involving living cells. A high shear rate may harm cells, for example in wine fermentation processes. In the bulk solution, the shear rate is also a measure of the degree of mixing.
