Abstract

The application of a new stochastic turbulence model for curved channel flow is presented. The numerical computation was performed using the finite volume method on colocated variable arrangements and SIMPLE based pressure-correction method was used to treat the velocity-pressure coupling. The widely used approach for computation of laminar flow was extended by the discretization of the turbulent Reynolds stress tensor modelled by the new stochastic turbulence model of Czibere [1]. In this paper an application of this turbulence model is shown for curved channel flow. The computed velocity field was compared with the experimental data measured by LDV.
