Curvature effects on twodimensional turbulent wall jets Numerical analysis with twoequation model of turbulence
Abstract
A modified version of an algebraic twoequation turbulence model is used to study the effects of surface curvature on the development of turbulent wall jets along plane, concave, and convex surfaces of constant radii. Velocity profiles, downstream development of halfwidth and maximum Reynolds stresses, and turbulent energy balances are well predicted by the model over a curvature range b/R = 0.1 to 0.1, where b is the halfwidth of the wall jet and R is the radius of surface curvature. For larger curvatures, the predictions of advection and nearwall production are less good.
