A variable-coefficient model for decay of isotropic turbulence capturing effects of finite cascade time and Reynolds number
Rozie Zangeneh, Wenyuan Xue, Daniel Israel +1
We study isotropic turbulence decay in the context of the k-epsilon model, which solves the dissipation and kinetic energy equations. In modeling the dissipation equation, the coef…

Reynolds stress decay modeling informed by anisotropically forced homogeneous turbulence
Ty Homan, Omkar B. Shende, Ali Mani
Models for solving the Reynolds-averaged Navier-Stokes equations are popular tools for predicting complex turbulent flows due to their computational affordability and ability to pr…
