Key Points

To validate a CFD program that employs central difference calculus for modeling turbulent pipe flows.
Studied two-dimensional turbulent parallel pipe flows using Navier-Stokes equations.
Increased viscosity in regions prone to solution divergence.
Applied the method to simulate three-dimensional turbulent parallel pipe flows.
Method proved effective for three-dimensional flows.
Calculated pipe friction coefficient was higher than at set Reynolds number but consistent with average internal Reynolds number.

Implication

Turbulence analysis demonstrates effective three-dimensional pipe flow simulation, suggesting improved computational fluid dynamics applications.
