The model attempts to predict turbulence by two partial differential equations for two variables, ''k'' and ω, with the first variable being the turbulence kinetic energy (''k'') while the second (ω) is the specific rate of dissipation (of the turbulence kinetic energy ''k''). ==Standard (Wilcox) ''k''–ω turbulence model == The eddy viscosity νT, as needed in the RANS equations, is given by: , while the evolution of ''k'' and ω is modelled as: $$ \begin & \frac + \frac = P - \beta^ * \rho \omega k + \frac \left(+ \sigma_k \frac \right)\frac\right ), \qquad \text P = \tau_ \frac, \\ & \displaystyle \frac + \frac = \frac P - \beta \rho \omega^2 + \frac \left(\left( \mu + \sigma_ \frac \right) \frac \right ) + \frac \frac \frac. \end For recommendations for the values of the different parameters, see . 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「K–omega turbulence model」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
