Abstract: Control equations of Bingham fluid are presented   according to the Bingham fluid
constitution equation. The pressure field and velocity field are correlated by a pressure-correction equation. Using the staggered grid, the non-physical pressure oscillation can be efficiently diminished. The numerical computations are performed for Binghem fluid in a pump impeller.
Keywords: Bingham fluid, pump, turbulent flow.
