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 ...

In this paper the analysis of water distribution networks consisting of a large number of pipes is studied.

The Newton’s method is used for solving the non-linear system of continuity equations which are written

in ...

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 exposed, which although...

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 ...

configuration), and a recirculation loop of the sludge (pipe flow (PF) configuration). The HRI configuration is equipped with a motor and a torque-meter allowing in situ determination of sludge rheogram under stirred reactor conditions. On the PF configuration...

In this paper, second-order explicit Finite Volume (FV) Godunov type scheme is applied for water hammer problems and the results are analyzed. The developed one-dimensional model is based on Reimann solution of continuity ...

Non-uniform heat flux distribution as a wall boundary condition is used for laminar developing pipe flow to find the optimum case which generates the least entropy. Several cases with different heat flux distribution but the same heat transfer rate...
