The motivation of this work is to investigate a grooved surface’s drag reduction. The viscous flow
through a two-dimensional microchannel with the grooved surface is analyzed by the lattice Boltzmann method
(LBM). The effects of the grooved surface on the streamline patterns, the velocity distributions near wall region
and the fluid shear stress distributions on the walls at different Reynolds numbers are studied. In addition, the
influences of the groove’s geometrical parameters on the grooved surface’s drag reduction are discussed. The numerical
results confirm the grooved surface’s drag reduction and present the drag reduction law of the grooved surface.
