Abstract

Valveless micropumps are crucial components in microfluidic systems and lab-on-a-chip technology.

These pumps, utilizing specific mechanisms, can transport fluids at the microscale with minimal clogging and damage to biological materials. In this research, the performance of a valveless micropump under laminar flow conditions (low Reynolds numbers) was numerically simulated. The aim of this simulation was to investigate the effect of flap height on pump efficiency and to better understand its operating mechanism. Results show that increasing the flap height leads to an increase in the volume of fluid pumped from left to right over time. By utilizing fluid-structure interaction, it was possible to analyze the fluid flow and structural deformations resulting from it.
