TrueGrid® CFD Model of the Fluid in a Volute for a Centrifugal Compressor
The area of the cross section of the volute grows linearly with respect to
rotation around the volute. Each cross section is a five block butterfly. A
splitter vane region, which separates the two regions of the volute where it
crosses itself, is highly resolved to capture the curvature and fluid action.
The geometry is in the form of a set of 2D spline knot points every 15
degrees. This is easily meshed with TrueGrid®.
