This paper presents a hybrid finite volume/finiteelement method for the incompressible generalized Newtonianfluid flow (Power-Law model). The collocated (i.e.non-staggered) arrangement of variables is used on theunstructured triangular grids, and a fractional step projectionmethod is applied for the velocity-pressure coupling.The cell-centered finite volume method is employed to dis-cretizethe momentum equation and the vertex-based finiteelement for the pressure Poisson equation. The momentuminterpolation method is used to suppress unphysical pressurewiggles. Numerical experiments demonstrate that the currenthybrid scheme has second order accuracy in both space andtime. Results on flows in the lid-driven cavity and betweenparallel walls for Newtonian and Power-Law models are alsoin good agreement with the published solutions.
