In this paper, transient flow in a pipe at Reynolds numbers (based on bulk velocity and diameter) ranged from 7000 to 45200 is numerically simulated using four common turbulence models. The models considered are the Baldwin-Lomax algebraic model...

The study of unsteady turbulent pipe flow is of value in providing information which can lead to an improved understanding of the phenomenon of turbulence. In such flows certain fundamental aspects of turbulent flow are ...

Abstract— In this paper, the modification of SST turbulence model for an accelerated flow in a pipe is studied. In order to determine the characteristics of the fluid under the non-periodic accelerating conditions and using water as the working...

In this paper, a 3D forward curved (FC) centrifugal fan is simulated numerically to predict the

turbulent flow and pressure field of the fan. Through this numerical simulation, the various

turbulent models are compared...

In this article, the kinetic energy–preserving (KEP) scheme and, also, the way of applying

this scheme to the k–ε turbulent model are introduced. This study aims to introduce a stable

method in which a few artificial dissipation terms...

algorithm. Grid-function convergence tests are utilized to verify the numerical results. The complicated laminar flow structure in the VSB is investigated, and preliminary assessment of two popular turbulence models, k-epsilon and k-omega, is conducted....
