Pulse-Burst Laser for Highly-Resolved Flow Field Measurements in both Space and Time

Abstract

DoD HBCU/MI program funds ($600,000) have been used to purchase a MHz rate pulse-burst laser to enable time-resolved measurements of various high-frequency flow properties. This laser directly interfaces with existing high-speed cameras and related devices in the AME Department at UArizona enabling advanced flow measurements for fundamental research and computational model development and validation. The laser indirectly supports the research of over a dozen AME faculty members with four primary experimentalists (Profs. J. Little, S. Craig, J. Jacobs, and I. Wygnanski) covering low-speed to hypersonic flows. This equipment will also foster existing and new collaborations with UArizona faculty in other strong units (e.g., Optical Sciences) as well as minority-serving institutions across the American Southwest.
