摘要
The characteristic features of the formulation of a two-layer turbulence model and its application in calculation of near-wall turbulent flows are considered. Factors that influence the effectiveness of implementation of the model and ways of expanding the limits of its applicability are discussed. The possibilities of the two-layer model are demonstrated by calculating a boundary layer on a flat plate with a longitudinal pressure gradient. A comparison of the results of calculation of the heat-transfer characteristics by the two-layer model, two-parameter dissipation model, and Spalart-Allmaras model with the data of a physical experiment and available correlations is made. © Springer Science+Business Media, Inc. 2007.
