Density-PDFs and Lagrangian statistics of highly compressible turbulence
چکیده انگلیسی

In isothermal, highly compressible turbulent flows, density fluctuations follow a log-normal distribution. We establish a connection between these density fluctuations and the probability-density-functions (PDF) of Lagrangian tracer particles advected with the flow. Our predicted particle statistics is tested against large scale numerical simulations, which were performed with 5123 collocation points and 2 million tracer particles integrated over several dynamical times.
