Abstract :
A two-dimensional numerical
simulation study has been performed to model an
electrohydrodynamic (EHD) micropump. The
emphasis of this study was on simulating the
effect of the different geometric design
parameters on the micropump pressure head and
volume flow rate. The simulated design
parameters are the channel height, the emitter and
collector electrodes heights and widths, and the
interelectrode spacing and the spacing between
the electrode pairs. The micropump consisted of
several electrode pairs which each can be
considered as a pumping stage. The simulated
working fluid was HFE-7100 3M® thermal fluid.
One pumping stage were simulated where the
total pressure of the pump can be calculated as
pressure of one stage multiplied by the number of
stages. The numerical results were first validated
with published experimental data then were used
to identify the influence of the different design
parameters on the pump performance to obtain an
optimum design.
