Florian Menter paper presented on: XVI Congresso Brasileiro DE Engenharia Mecânica 16th Brazilian Congress OF Mechanical Engineering In spite of decades of research, there is no analytical theory to predict the evolution of these turbulent flows. The equations governing turbulent flows can only be solved directly for simple cases of flow. Discretization in the space produces a system of ordinary differential equations for unsteady problems and algebraic equations for steady problems.
