Second order modeling of turbulent flows
Abstract
A second order modeling scheme is constructed for turbulent flows by modeling the return-to-isotropy term, the rapid terms, the transport terms, and the dissipation terms. It is noted that the proposed scheme, when calibrated against a plane jet, overestimates the spreading rate of an axisymmetric jet by about 40 percent.
