Coupling of particle and continuum methods for the simulation of radiative and particle laden flows

Abstract

Particle methods are the method of choice for flow conditions at high altitude, particle-laden flows or radiative heat transfer. One big challenge is to provide an efficient coupling interface to established numerical methods for the continuum regime to be able to use a generalized user interface for all flow regimes. The chosen unified approach based on a plugin to the coupling software FlowSimulator provides a general python-based coupling interface. This allows the straightforward combination and data exchange between the numerical solvers, e.\,g. for the rarefied and continuum regions. The two-way particle coupling approach is demonstrated using Lagrangian particle test cases.
