Abstract

This chapter presents features of the standard k–ε model and some other two equation models. We first start with the steps for the derivations of the exact transport equations for k and ε and subsequently proceed to propose the modeled forms of these transport equations. We also suggest ways to handle walls and some other flow complexities using the k–ε model. We close this chapter by presenting the major potentials of the two equation models. We also present some examples where the k–ε model fails to accurately predict the flow behavior and needs to be modified.
