A Reynolds-averaged turbulence modeling approach using three transport equations for the turbulent viscosity, kinetic energy, and dissipation rate

摘要: A Reynolds-averaged approach to turbulent shear flows is sought with resort a three-equation method. Its novelty the introduction of turbulent-viscosity transport equation through for Reynolds stress in addition those kinetic energy and dissipation rate. The latter two equations are used evaluating dimensional coefficients former. aim this model enhance capability cope nonstationary advection effects various flows. adaptability them confirmed application homogeneous-shear supersonic free-shear In particular, reasonable prediction obtained where growth rate layer suppressed increase convective Mach number. present also applied three-dimensional flow past wing tip as an instance complex aeronautical flows, excessive diffusion trailing vortices shown be suppr...
