By using the method of direct numerical simulation(DNS), evolution of coherent structures in the wall region of a turbulent boundary layer with three different pressure gradients was studied. Initial values of the coherent structures in the wall region were obtained on the basis of the idea of resonant triad in the theory of hydrodynamic stability. It was found that the results of DNS match with those of the experiments very well in many aspects. The effects of pressure gradient on coherent structure were obtained by comparing the results of three different cases. |
