摘要
The diffusive information preservation (D-IP) method is utilized to simulate three-dimensional turbulent channel flow. The Knudsen number and Reynolds number based on the channel half-width and mean velocity are 5 square 10(square 5) and 2800, respectively. The averaged velocity profile and the higher order turbulent statistics obtained by D-IP agree well with the DNS results given by Kim, Moin and Moser. Turbulent mixing length and turbulent viscosity obtained by the present results based on kinetic analogy are found to be comparable with the classic theory of Prandl's mixing length and Boussinesq eddy viscosity.
