Test Data

Overview of Tests

An experimental validation was performed for two operation points, the partial load ( $Q=2.5~l/min$ ) and the nominal load ( $Q=4.5~l/min$ ) at a rotational speed of $n=7,900~r/min$ .

the numerical VAD model was explained in section >>Flow Domain Geometry<<. This was originally created exclusively for numerical investigations. In order to enable an adequate validation of the simulated VAD flow, the following requirements were placed on the experimental model during conceptual design:
