A second moment turbulence model applied to fully separated flows
Abstract
A turbulence model which has previously been applied primarily to boundary layer flows including geophysical flows is here applied to a fully separated flow. The full elliptic problem is solved and differential equations for all components of the Reynolds stress tensor are involved. All constants in the model have been determined from other more simple flows so that we need not appeal to 'computer optimization.' Calculations are compared to data obtained by Abbott and Kline. It is our understanding that the turbulence data are not accurate. Nevertheless, these data and the predictions compare reasonably well. The predicted mean velocity profiles and the point of reattachment agree very well with the data.
