In this paper, we mentioned to a numerical analysis method for simulation of a micropump for microfluidic applications. Each sections of the micropump, including microvalves and pumping chamber, were studied using three-dimensional fluid-structure interaction analysis and their operational characteristic equations were extracted independently. These extracted equations were used to solve time-domain pressure equation and to obtain the flow rate of micropump. Afterwards, we were able to study different effects of actuation pressure and actuation frequency on micropump’s flow rate with and without the presence of outlet backpressure. The results show that when actuation frequency is 1 Hz and actuation pressures is equal to 1000, 1500, 2000 Pa, pumping flow rate reaches to 30, 48 and 65 mm3/min, respectively. Also, this micropump can overcome maximum backpressure of approximately 950 Pa when it was actuated using pressure of 1000 Pa, regardless of its actuation frequency. These simulated results reasonably agreed to the microfluidic and lab-on-a-chip applications.
