Fluid shear stress may cause cell deformation in the direction of flow, thus leading to temporally varying and spatially heterogeneous stresses in the cell membrane to increase the cell membrane.

i.e., Newtonian fluid, is yield stress. Yield is the tendency for a complex fluid to flow as a liquid only above a nonzero critical shear stress. Put another way, a yield stress fluid can support its.

Laminar flow is a flow regime characterized by high momentum diffusion and low momentum convection. When a fluid is flowing through a closed channel such as a pipe or between two flat plates, either of two types of flow may occur depending on the velocity and viscosity of the fluid: laminar flow or turbulent flow. Laminar flow tends to occur at.
