Micro-Piv Of Self-Propelling Bi-Slugs In A Micro Channel, Lilla M. Safford Smith
Micro-Piv Of Self-Propelling Bi-Slugs In A Micro Channel, Lilla M. Safford Smith
Honors Theses
Bi-slugs are fluid entities involving two dissimilar fluids that move “on their own” due to differences in surface tension. At the micro-fluidic scale this sort of motion may be useful to efficiently transport small quantities of fluid from place to place. This study uses Micro-Particle Image Velocimetry (µ-PIV) techniques to investigate self propelling bi-slug flows. The bi-slugs examined are made of ethylene glycol and Xiameter PMX-200 Silicone Fluid (5cst and 10cst) and placed in a glass micro-channel of approximately 1mm diameter. The Reynolds number (Re) range considered (based on ethylene glycol in the slug) is 2.54 - 1.07 and the …
