In a previous paper a new type of laboratory test facility was introduced, that enables experimental modeling of rotating and fixed pump components respective electrochemical and mechanical wear. The effects of velocity, gap width and erosion-corrosion in a CO2 multiphase environment had been shown. This paper discusses the results of experiments conducted on the new test facility with a set of pressure sensors integrated in the flow path of the fluid in the crevice. It will be shown how the ascertained pressure sensory data can be used to calculate the radial component of the fluid velocity vectors. Numerical calculations will be used to calculate the tangential component of the vector resulting in the total speed and direction of the crevice flow. As a conclusion for the modeling of multiphase pump components, the two dimensional vector velocity field of the fluid flow in rotating disc crevices at different rotational speeds will be presented in charts displaying both the total velocity and direction of flow.
