Abstract

In this paper, the dissipative particle dynamic method is used to simulate the electrosmotic micro pump as the main part of a spatial-chemical propulsion system. In this simulation, the micro-pump is driven by the principle of  electrosmotic flow.Furthermore,the effective parameters, such as channel dimensions, applied voltage, surface effect, or zeta potential are analyzed. This research focuses on developing a simulation method for applying external force (electrosmotic force) as well as developing a method to a channel with different sizes and conditions. Our results include velocity profile in a channel with different effective parameters. The result were compared with and validated by analytical solution. It was shown that the electrosmotic method is an ideal method for transferring fluid as a micro-pump in different conditions and also in fine-scales applications, such as in micro-satellites.
