In this paper, we give an overview of turbulence modelling and turbulence in general, followed by an implementation of the Lam–Bremhorst k-ε turbulence model in FEniCS. We demonstrate how the model can be easily implemented in the latest version of FEniCS, even when working with the simplest methods and schemes. We hope this paper serves as a valuable resource for researchers and enthusiasts seeking a straightforward introduction to turbulence modelling and a practical guide for implementing models in FEniCS.

摘要

In this paper, we give an overview of turbulence modelling and turbulence in general, followed by an implementation of the Lam–Bremhorst k-ε turbulence model in FEniCS. We demonstrate how the model can be easily implemented in the latest version of FEniCS, even when working with the simplest methods and schemes. We hope this paper serves as a valuable resource for researchers and enthusiasts seeking a straightforward introduction to turbulence modelling and a practical guide for implementing models in FEniCS.
