Validation of code using turbulence model applied to three-dimensional transonic channel

The flow induced by a swept bump mounted on the lower wall of a transonic channel has been thoroughly analyzed on the basis of surface pressure measurements, surface flow visualizations, and field measurements by a three-component laser Doppler velocimeter system. The same flow has been computed by a code solving the full time-averaged Navier-Stokes equations by a method using an explicit centered finite difference scheme applied to a finite volume approach. An algebraic model using the mixing length concept and the Jones-Launder [k, e] transport equation model have been considered. Both models give a faithful prediction of the essential features of the flow; in particular, the shock pattern forming in the channel is well predicted. However, the [k, e] model shows a clear superiority in the prediction of the behavior of the interacting dissipative layers
