AN ANALYTICAL STUDY OF THE STANDARD K-EPSILON MODEL

An asymptotic solution of the standard κ-ε model for two-dimensional turbulent channel flow is found. Using this solution, five model constants in the model are all determined reasonably with the aid of experimental data. If an asymptotic solution with the logarithmic law as the leading term is sought for, the standard κ-ε model is shown to be ill-posed since the second-order solution has divergent terms. © 1990 by ASME.
