A Multiscale Morphing Continuum Analysis on Energy Cascade of Compressible Turbulence

Abstract

This project presents the kinetic nature of the morping continuum theory and its application in compressible turbulence andnonequilibrium phenomena at high Mach number. Numerious publications have indicated that morphing continuum theory iscapable of predicting high speed and compressible turbulence physics without requiring heavy computational resources -saving about an order lower than the classical N.S.-based DNS for grids. The 2D and 3D test cases includes incompressibleturbulence of Re~1M, supersonic turbulence of Mach 3 and transonic turbuelnce with weak shock. Morphing continuumtheory can successfully capture the shock structure and heat transfer at high Mach number (Ma~10)
