General information - Fan with no Housing

In the following tutorial, there will be shown the methodology of simulating and evaluating radial (centrifugal) fan using Turbomachinery CFD. This tutorial deals with centrifugal fan, the wheel diameter img27 3img94 1img316img317, total pressure difference img318img94 1img319img91 2. The compressible fluid flow model. The fan has no housing. The computational geometry of this fan case is depicted in Figure (crossref 2). In this particular case the whole wheel is computed, nevertheless the single blade periodic case is possible. In the periodic case the approach would be almost the same.
