Implementation of Both a Second-Moment Closure and a Third-Order Nonlinear Eddy-Viscosity Turbulence Models to KIVA-3V Code 2003-32-0028

A second-moment turbulence closure and a third-order nonlinear eddy-viscosity model, which are expected to show better performance than the linear eddy-viscosity model (the standard k-ε model) in swirling and tumbling flows in engine cylinders, have been incorporated to the engine CFD code KIVA-3V [1,2,3]. Test calculations have been carried out in order to compare characteristics of these models.
