Anisotropic Synthetic Turbulence with Sweeping Generated by Random Particle Method

Abstract

We develop an efficient method to generate convecting synthetic turbulence in complex mean flows. In this article we present the extension to anisotropic turbulence, realistic spectra and sweeping effects, i.e. the advection of inertial range structures by the energy containing large scales. We show that due to this formulation sweeping effects can be included and the spatial-temporal field shows the similarity of Kraichnan’s sweeping hypothesis.
