Conditional Second Order Closure for Turbulent Shear Flows.
Abstract
Second order turbulence closure models for conditional moments and the intermittency factor were developed. Methods for the treatment of turbulent/non-turbulent and other scalar interfaces were applied to the plane mixing layer and round jet. Multiscale closure models based on the dissipation rate were developed and applied to homogeneous turbulence and the plane jet. Scalar transport was investigated using the separation probability of clusters of particles and numerical solutions based on stochastic simulation techniques. A direct extension of conditional closure to velocity-scalar pdf equations was also developed.
