FLOW DISTRIBUTION CONTROL IN MESO SCALE VIA ELECTROHYDRODYNAMIC CONDUCTION PUMPINGPublic
Downloadable Contentopen in viewer
Electrohydrodynamic (EHD) conduction pumping offers a unique way to control flow distribution for heat transfer applications. In EHD conduction, the interaction between an applied electrical field and dissociated electrolyte species in a dielectric fluid creates a net body force within the fluid, resulting in flow. EHD conduction pumps have remarkable potential due to their lack of moving parts, low power use, and ability to operate in microgravity. This study examined EHD distribution control among three 1 mm-diameter parallel tubes. The EHD pumps were able to correct maldistributed flow in flow lines and were able to cause maldistribution when even flow was initialized. The EHD pumps were operated between 0V and 1500V with flow rate supplies of 3mL/min and 25mL/min.
