Abstract

This paper presents a new method for simulating ship airwake flow fields. These flows are inherently unsteady, and very difficult to predict. The method presented (NLDE) is fourth-order accurate in space and time. In this method we first solve for the steady state flow field, then we solve for the unsteady fluctuations. Steady and unsteady results are presented for a generic frigate shape. The parallel method is a necessity for ship air wake problems and MPI is used in the NLDE solver. The parallel performance on various computers is compared also.
