This paper describes the development of a post-processing method for a set of steady-state finite volume method results to make a pseudo-transient cavitation prediction for propellers in behind hull condition by interpolation. At the time of writing, predicting the propeller cavitation in behind hull condition requires a time-consuming transient calculation with a dynamically rotating mesh for each operation point under consideration. In order to speed up this process an approach is developed where the solution field of a steady propeller open water performance calculation is rotated in relation to a vessel’s wake field. During this rotation, the wake induced shift in the propeller’s operation point on each cell of the simulation is used to interpolate over the calculated solutions. This workflow is tested with the known Potsdam Propeller Test Cases for homogeneous and oblique inflow. A good agreement between higher quality computational methods and the calculated prediction is achieved.
