Abstract

The hot-wire anemometry measurements obtained in an eight-degree conical diffuser indicate the relative importance of advection and turbulent diffusion of kinetic energy to the energy production and dissipation. The present computational effort has developed in two directions. First, prediction of the mean velocity profiles is currently being studied. Second, an existing low Reynolds number k - ε closure is being modified to predict this flow. It is expected that the modified closure can be used for similar decreasing adverse pressure gradient flows.
