Research Description

Interfacial Flows
In fluid mechanics, one of the most fundamental concepts is the no-slip boundary condition, which says that the fluid in contact with a surface moves with that surface or has the same velocity of the surface. In most situations this condition is axiomatically accepted, and more over yields realistic results. However, cases in which a fluid interface moves along a solid surface (e.g. a small droplet sliding down an inclined plane or waves in the ocean bobbing up and down on a ship hull) is clearly in violation of the no-slip condition. Mathematically speaking, there is then a discontinuity of the fluid velocity at the triple contact point and hence a singularity in the fluid stress. This research project will focus on investigating the fluid flow very near the triple contact line. In order to achieve a better understanding of the phenomenon that is occurring, several micro particle image velocimetry (micro-PIV) experiments will be conducted. Micro-PIV is an optical technique used to measure velocity fields in physically small regions. The fluid motion that will be studied will be initiated by an apparatus consisting of a microchannel in which a liquid will be dispensed and transported (e.g. by a syringe pump). From the data obtained through the experiments, the goal is to be able to better characterize and model interfacial flows as they approach the triple contact point where there is currently no way to describe the behavior that is demonstrated by the fluid.
