Abstract

This paper expands on the numerical simulation of entropy noise by performing a comparison of two commonly used models for resolving turbulent flow field: Large Eddy Simulation and Unsteady Reynolds Averaged Navier-Stokes. A brand new numerical procedure was developed allowing an accurate reproduction of two-dimensional spatial and temporal temperature variations of a non-uniform temperature profile. Experimental investigation was performed for the same non-uniform temperature profile, and comparison of the entropy noise level measured experimentally and evaluated numerically using the two models was performed. It was shown that Large Eddy Simulation allows a better prediction of entropy noise within the developed numerical procedure than Unsteady Reynolds Averaged Navier-Stokes.
