Abstract

This paper presents a coupled Vortex Particle Method-Computational Fluid Dynamics solver. The Vortex Particle Method solution is used to correct the Computational Fluid Dynamics. This is achieved by using the Split VelocityMethod, which includes the influence of the particles through their induced velocities and additional source terms. The coupled solver is demonstrated on a two-dimensional and three-dimensional test case and the results are compared to the solutions of the CFD solver on its own using a coarse mesh and a fine mesh. It is shown that the hybrid solver preserves the tip vortex on a coarse mesh and is computationally more efficient than using the fine mesh.
