Closure model for intermittent turbulent flows
Abstract
A closure model for turbulent shear flows based exclusively on conditional moments and the intermittency factor is developed. The model contains the equations for intermittency factor, the turbulent zone and non-turbulent zone mean velocities and kinetic energy and dissipation rate for the turbulent zone. The model is applied to the prediction of plane jets and boundary layers and gives satisfactory results for intermittency factor and first order moments.
