APPLICATION OF WALL FUNCTIONS TO GENERALIZED NONORTHOGONAL CURVILINEAR COORDINATE SYSTEMS

A method has been developed for the application of wall functions to g eneralized curvilinear coordinate systems with nonorthogonal grids. Tw o test cases have been computed using this method with the k-epsilon t urbulence model: now over a flat plate at 0-deg angle of attack using a nonorthogonal grid at the wall and now over a prolate hemispheroid w ith a hemispherical nose cap at 0-deg angle of attack. All results are compared with experimental data. In addition, the hemispheroid result s are compared with computations using the Baldwin-Lomax algebraic tur bulence model and the Chien low-Reynolds-number k-epsilon turbulence m odel.
