中文摘要The two-dimensional Kolmogorov flow generated by an imposed unidirectional forcing varying sinusoidally in space is simulated by using direct simulation Monte Carlo method. Our simulation is performed under the condition of Knudsen number Kn=0.005 and forcing wave number k(f) = 4. When the Reynolds number Re exceeds the critical value Re(c) = root 2, the basic shear flow becomes instable and changes to cellular structures. As Re increases, two main regimes of the flow have been observed: small scale structure (Re(c)7Re(c)). When large scale structure is formed, the energy is inversely transferred from small scale forcing to large scale structure. As Re continues to increase, the evolution of flow field successively becomes quasi-periodical and irregular. This behavior provides a reasonable transition to turbulence with further increase of Re.
