In order to develop the vortex generator jets method for flow control, the far-field and near-field of the counter-rotating vortex pairs produced by a pair of inclined round jets embedded in turbulent boundary layer are studied numerically. In the calculation, the incompressible RANS (Reynolds Averaged Navier-Stokes) equations with the standard and RNG k-ε turbulence model were solved using the commercial code STAR-CD which employed the unstructured mesh. The typical results are compared with the experimental data. The effects of jet parameters such as velocity ratio on the strength of the vortices generated by the jets are investigated. The results do clarify some physical mechanisms of the flow field generated by a pair of pitched and skewed jets.
