Applied Mathematics Seminar: Fast Semi-Implicit Lagrangian Particle Tracking of Polydisperse Particles

Speaker Info:
Som Dutta, Mechanical and Aerospace Engineering, Utah State University

Abstract: Lagrangian particle tracking, and the related point-particle models are an efficient and effective way to track coherent structures in a flow, and model transport of particulate matter. Applications of point-particle models range from sediment transport in rivers, to atomization of fuel in an internal combustion engine.

We propose a fast semi-implicit time stepping scheme for integrating the equations used for Lagrangian tracking of particles with inertia.

In the second part of the presentation, we talk about a novel scheme to accomplish the most expensive part for any Lagrangian particle tracking calculation, the interpolation step, where the velocity field (and others fields) from the Eulerian grid is interpolated to the location of the particle.

I will close the presentation with a brief overview of different types of fluid dynamics the phenomena I am working on, and are interested to explore in the future.
