Stability analysis for the occurrence of Taylor-Gortler vortices in turbulent wall jets along concave surfaces is made in a comparative experiment. The eddy viscosity expression in the perturbation equations is derived from a modified version of a two-equation in the perturbation equations is derived from a modified version of a two-equation turbulence model including curvature, which predicts well the main features of the turbulent wall jets along concave surfaces. Through the stability analysis, it is found that the minimum curvature at the neutral stability state decreases slighly as the Reynolds number increases. Then, the eddy viscosity expression is treated as a function of curvature.
