The drag force acting on a cell adhered to the bottom plate of a parallel-plate channel exerted by the fluid flow is numerically analyzed, and the value is compared to the corresponding one evaluated by a conventional method for a spherical particle adhered to a plane wall subject to an unbounded simple shear flow. As expected, the two values coincide with each other when the size ratio of the cell-to-channel height is very small. As the size ratio increases from zero up to approximately 0.2,the drag force acting on an adherent cell decreases linearly, almost independently of the separation distances between neighboring cells. For larger size ratios, the drag force in channel flow varies drastically, depending on the size ratio and the separation distances, and it is generally smaller than the corresponding value in the tube flow, even when the wall shear stress is identical.
