A Numerical Method for Tracking the Deformation of Fluid Particles


Article Preview

A model for the deformation of fluid particle under the action of velocity gradient tensor is proposed in this article. In this contribution, the control volume/surface is geometrically simplified into micro-ellipse. By using a series of changes of basis and eigenvalue decomposition, a numerical method for the deformation of an elliptic fluid particle is then demonstrated. Finally, this method is applied in two different problems involving smoothed particle hydrodynamics (SPH) simulation and a passive scalar turbulence case.
