Hi, I have been researching that whether piezoelectric ceramics can create enough force on the fluid flow to change its direction in the microfluidic channels. I designed a basic microfluidic structure (3 inlets, 2 outlets) in Comsol. However, I cannot combine the piezoelectric ceramic vibration effect and laminar flow in the microfluidic channel in Comsol. Does anyone have a similar interest? Thanks in advance.
