Abstract
Turbulent flow in a two-dimensional channel is numerically simulated by the large eddy simulation (LES) technique. A finite difference scheme with about 3.83 million grid points is applied to the case of the Reynolds number 5840. Turbulence statistics are compared with the experimental data and the results of recent large-scale computations; agreements are quite reasonable. Numerical results are stored as a database for the purpose of studying the turbulence structure and the modeling in the near-wall region. As the first report in a series on this research, this paper presents the balance of the terms in the transport equations of the turbulence kinetic energy, the dissipation rate and the Reynolds stress tensor.
