Numerical Simulation of Pulse-Width-Modulated Micropumps with Diffuser/Nozzle Elements

Nguyen N-T., Huang X., Nanyang Technological University, SG

This paper presents the numerical simulation of a new control method for dynamic micropumps with diffuser/nozzle elements: the pulse-width-modulation (PWM) of the drive signal. A piezo disk with a square wave signal actuates the pump, [...]
