Abstract :
The flow behaviour in a valveless micropump is analyzed using the Fluid Structure Interaction (FSI) method. To accurately predict the working behavior of the micropump based on the fluid equations, structural equations and piezoelectric equations, the fluid-structure dynamic coupling effects should be taken into account. Accurate analysis of fluid-structure interaction of the micropump involves in electro mechanics, solid mechanics and fluid mechanics. Because of the complexity of the micropump, the analytic flow solution is impossible, and the full 3D numerical solution is extremely difficult. To overcome this, it is ideal to carry out 3D-FSI simulations to investigate the micropump in details.
