Accelerated Turbulent Pipe Flow Study Using Various Turbulence Models

The study of unsteady turbulent pipe flow is valuable because it provides insight information to understand the phenomenon of turbulence. In such flows certain fundamental features of turbulent flow exist, which although present in steady turbulent flows are not apparent under such conditions. Unsteady turbulent pipe flows can be conveniently classified into two groups, namely periodic pulsating flows and non-periodic transient flows.
