The next design step is to create the meridional contour of the impeller. On the right side, you see a sketch of the meridional view and the Cordier diagram. The user has the capability to use automatic mode, or to modify any of the main dimensions manually. To define the main dimensions of the impeller, CFturbo uses fundamental equations and empirical correlations. Here, you have to choose the number of blades, which could be between one and three. In this example, we will create a wastewater pump. Now we add a new component, choosing the radial mixed-flow impeller option. After choosing the design point, on the right side you’ll see the specific speed and the general machine type of the pump. The user must set volume flow rate, head, and rotational speed. In the global set-up the design point must be defined. This video is about the hydraulic design and CFD-simulation of a wastewater pump.įirst you create a new project choosing the pump design module.
