(Note that the c, as used here differs from the C,, defined in Eq. (4).) For the high Reynolds number flow under consideration, only stress terms in the normal direction are retained. In addition, convection and diffusion processes are neglected. Under these assumptions the energy equation reduces to where R will be the streamline radius of curvature and ( is an empirical constant on the order of 10. For this investigation a different correction formula, suggested by Baldwin (private communication), was used. This correction is derived from Prandtl’s turbulent kinetic energy equation with a curvature suppression term, F,, suggested by Baldwin, Chigier, and Sheaffer!! in 1973 for a k — € model. In the notation of Rodi!” the steady kinetic energy equation with the curvature suppresion term suggestion by Baldwin. et.al!! is written as
