Direct Numerical Simulation of the Influence of Plasmas on Turbulent Flows

Abstract

This work uses direct numerical simulation to study the thermal effect of a region of plasma on quiescent air. The simulations solve the compressible ideal gas Navier-Stokes equations using Fourier spectral methods. A shock capturing scheme is incorporated to account for the strong shock waves. Also, a logarithmic formulation for the continuity equation is developed to handle low densities at the core of the plasma.
