I have worked with SSA on CFD analysis of various rotodynamic pumps, most recently using the STAR-CCM+ software. We were particularly looking for performance prediction, areas with high losses and recirculation flow patterns. SSA go to great lengths to produce the most accurate analysis that they can and have been excellent in presenting results in an understandable manner. They are always prepared to change the method of presentation to suit my requirements whilst keeping costs within budget. Geoff Lake, Lakeflow Engineering Consultants Ltd
