Abstract
The development of turbulent boundary layers with blowing or suction in zero or finite pressure gradients is calculated using a second-moment closure that is applicable right up to a wall. The turbulence model was previously shown to give good predictions for several types of flow, including a rotating channel flow. In the present calculation, no special changes are made to deal with transpiration, except for a wall boundary condition fro the normal velocity. Published experimental data on the friction coefficient, the mean velocity profiles, and the turbulent normal stress profiles are used to assess the performance of the model calculation. It is shown that the numerical solutions are generally in agreement with the data. This paper thus shows the wide applicability of the turbulence model.
