Abstract
AbstractThis paper reviews past and current efforts in developing a simple but robust turbulence model for free shear flows. Much of this work has been published previously and this paper is a rearrangement aimed at the conference. The model is presented and is interfaced with FIDAP to solve three‐dimensional flows and a pusher—prop configuration. The eight‐node brick, the penalty formulation and the Broyden method are used to solve the Navier‐Stokes equations. The propeller is modelled as an actuator disc and the direct simulation of a given propeller is considered in detail. Good results are obtained for the square jet. For propeller cases detailed comparison with wind tunnel measurements shows excellent prediction of the velocity and pressure for flows of this complexity.
