The aim of this research is a better understanding of the basic particle dynamics in dilute sheared suspensions at different length scales. This work began with the study of inertial and geometric effects on particle-fluid coupling in a dilute sheared suspension.
Current work involves the direct visualization of nanoscale particles at an interface.
Project Design Developed a technique for measurement of nanoscale particle concentration at an interface. Designed an actual scale facility to simulate CMP, allowing visualization and evanescent wave illumination of nanoscale particles at polishing surface. Used PIV, LDV and particle visualizations to investigate particle-fluid interactions of noncolloidal particles. Publications Moderate aspect ratio elliptical cylinders in simple shear with inertia.
