Abstract:

The fluid flow of turbulence through the tube and the channel is important in fluid matters. It is well known that, in the framework of isotropic or eddy viscosity turbulence closure modeling, good predictions of the mean and turbulent flow fields rely on reasonable descriptions of the turbulent length scale and velocity scale inside the flow field. The inconsistency of the standard k - epsilon model is very often attributed to the dissipation rate equation which is highly empirical in nature. Improvement of the model performance is usually achieved by modifying the dissipation rate equation. In this paper, the speed and distribution of pressure along the pipe and channel are calculated and compared with each other.
