K-εモデルの二次元平行平板間の流れの近似解

概要

論文の詳細を見る
An approximate solution of the standard k-ε model is found for two-dimensional turbulent channel flow. Here, k is the turbulent energy, and ε the dissipation rate of kinetic turbulent energy. Using this solution, five constants used in the model are all determined reasonably with the aid of experimental data. If an approximated solution with the logarithmic law as the leading term is sought, the standard k-ε model is not applicable since the second-order solution has divergent terms.
