As mentioned previously, RBCs are known to be damaged at high levels of shear rates and wall shear stresses. In this work, four types of mesh types were analyzed: coarse (, Similar to the simple square electrode design, the fluid flow in the proposed design microchannel is steady from both inlets and becomes unsteady (, Similar to the simple square electrode design, the key argument here is that although the fluid flow is unsteady, it provides a smooth transition for both RBCs and platelets to be trajected from the inlets to the outlets. Using COMSOL Multiphysics, we can solve the governing equations for fluid flow, the Navier-Stokes equations, to determine the velocity and pressure fields that describe the flow.
