2D Incompressible Flow Numerical Modeling of LSMPS Vortex Particle Method using Ellipsoidal Particle
Abstract
Particle-based fluid simulation has been vastly developed in the recent age. In our groups, a vortex particle method (VPM) is developed using LSMPS method and Brinkman penalization. One of the issues in our program is to enhance performance since it still has a high computational cost. The particle distribution technique of ellipsoidal particles is a new method that intrigues this work. In this paper, the LSMPS–VPM fluid simulation program is being modified by ellipsoidal particle distribution. It was tested on a laminar boundary layer on a flat plate. The results have a significant computation cost reduction with computation time saved up to 53% and even more. The error increase is low and linearly proportional towards the elliptical ratio. By this result, it is very potential to implement this ellipsoidal particle technique on other fluid solvers in reducing the computational cost.
