The plane turbulent impinging jet
WebbA modeling to turbulence is screened in which the Reynolds stress appearing in the momentum equation is charged from the language \(\overline {u'\upsilon '} = - \sqrt k L(\partial U/\partial y)\); the kinetic energy, k, and the extent scale,L, of turbulence are determined from differential transport equations for these quantities.Those equations … Webb2 mars 2024 · This paper investigates the maximum wall shear stress value τ max and its location x max as measured on a smooth flat plate impinged upon by a normal planar …
