This course offers a hands-on introduction to CONVERGE for compressor and pump modeling. Although compressors and pumps can feature significantly different geometries and motion types, all compressor and pump simulations benefit from CONVERGE's autonomous meshing capabilities. In addition, many benefit from CONVERGE's fluid-structure interaction modeling, multiple reference frame approach, advanced fluid property models, and other features. We will examine a variety of example cases for both positive-displacement and dynamic devices, including a scroll compressor, a screw compressor, a single channel pump, and a centrifugal fan.
