and incompressible Hagen-Poiseuille flow was numerically simulated with GAO-YONG turbulence model using SIMPLER(Semi-Implicit Method for Pressure-Linked Equations) method and PLS(Power Law Scheme).As a result
the calculation successfully simulates the flow and predicts the fundamental properties of the boundary layer
including the natural transition process
which are close to the experimental data.It verifies the adaptability of GAO-YONG turbulence equations to real turbulent flow.
