Graduate Seminar Series – Dr. Daniel M. Israel, LANL

Title: RANS Modeling for Taylor-Green Vortex Transition and Decay By: Daniel M. Israel, Ph. D. XCP-4: Methods & Algorithms, Los Alamos National Laboratory ABSTRACT: Conventional RANS models relate the destruction terms in all transport equations by tunable linear coefficients. This fixes a constant decay rate in homogeneous decaying turbulence, contrary to experimental evidence. It also cannot…
