Turbulent Transport of Momentum and Scalars in Swirling Flows with and without Combustion
要約
Effects of swirl on turbulent transport of momentum and scalars (heat and mass) are described, based on the reviews of experiments and numerical analysis of swirling flows. They include turbulent flows in a pipe rotating along its axis, in an annulus with a rotating inner cylinder, and in a stationary tube with swirl. Factors affecting the retardation and promotion of turbulent transport due to swirl are illustrated, paying attention to the production terms in transport equations of turbulent fluxes of momentum and scalars. Variable density effects in swirling flows are also described. Numerical computations incorporated with turbulence models are compared with experiments with and without combustion to reveal the applicability of the models.
