Abstract

Radial flow pumping rings receive the flow radially which is perpendicular on the shaft while axial flow pumping rings receive the flow in a direction parallel to the shaft (axially). An experimental investigation is carried out to evaluate the single axial pumping ring performance with a non API design radial clearance. The experimental setup is constructed according to API plan 53B with an accumulator-based seal support system in the barrier circuit loop. Furthermore, a numerical investigation is conducted to provide a reliable numerical model represented by ANSYS Fluent by creating an acceptable meshing and turbulence modeling using the experimental results as a validation method. As for the numerical investigation, it is indicated that K-epsilon realizable turbulence model is the best numerical model in terms of the least error deviation between the numerical model’s performance curve and the experimental performance curve.
