Аннотация

Numerical simulations of two-dimensional and three-dimensional laminar jets impinging on flat surfaces were performed by solving nonsteady Navier-Stokes and energy equations. Results show flow structures and heat transfer on the impingement surfaces as function of the geometry and Reynolds number. Steady flows were obtained for Reynolds numbers smaller than a critical value. Periodic flows appeared at Reynolds numbers larger than the critical value. At still higher Reynolds number the flow became unsteady nonperiodic.
