Abstract
A numerical analysis is made on the turbulent boundary layers with injection and suction through a slit using five different turbulence models. The five models are three eddy viscosity models (zero-, one- and two-equation models) and two different types Reynolds stress model. Published experimental data on the skin friction factor, the mean velocity profiles, and Reynolds stress profiles are used to assess the performance of the model calculations. Applicabilities of these models to the turbulent boundary layers with injection and suction are investigated. For flow with injection, the Reynolds stress model gives good agreement with the experimental data. The zero-equation model provides very accurate prediction for suction flow.
