Description
In the previous paper, the authors proposed a new κ-ε model and improved prediction accuracy of the mean flow field with longitudinal vortex. However, it was difficult to express normal Reynolds stresses accurately in view of Boussinesq assumption especially in high vorticity region. To improve this problem, the authors examined the nonlinear eddy viscosity expressions and combined them with the author's κ-ε model. Computation is performed around the SR196a ship stern form with the longitudinal vortex to clarify the validity of the nonlinear κ-ε model. The conclusion is that the nonlinear κ-ε model shows some improvements of the local trend of the normal Reynolds stress profiles.
