Various wall-bounded flows with complex geometries and free shear flows have been studied with a newly developed realizable Reynolds stress algebraic equation model. The model development is based on the invariant theory in continuum mechanics. This theory enables us to formulate a general constitutive relation for the Reynolds stresses. In our study, realizability is imposed on the truncated constitutive relation to determine the coefficient so that, unlike the standard k-e eddy viscosity model, the present model will not produce negative normal stresses in any situations of rapid distortion.
