High Velocity Multi-Particle Impact: Experimentation, Characterization, and Optimization

ZHERUI MARTINEZ-GUO

Faculty Candidate - AAE Open Search

ABSTRACT:
 
Multi-particle impact can be broadly defined as several particles impinging a target near-simultaneously, or the same spatial location consecutively within a short time span. High velocity multi-particle impingement occurs across a broad range of scenarios, such as windblown debris from severe weather patterns, damage in aircraft engines from ingested particulates, or micro-asteroid impact on space habitats and spacefaring vehicles. Ongoing efforts at the Purdue Impact Science Lab (ISL) have focused on solid particle erosion, which occurs when sand particulates get ingested and impact engine turbine blades under operational conditions. Recent collaborations with the Navy and Rolls-Royce Corporation are aimed at developing advanced erosion testing capabilities at Zucrow Labs to design better protective coatings for harsh engine conditions. The ISL also has an extensive history of collaborating with the scientists at the Advanced Photon Source (APS), Argonne National Laboratory to develop materials characterization methods and diagnostics for advanced blade coatings via high-speed imaging (up to 5 million fps), high strain rates (103–106/s), and ballistic impact velocities (~ 600 m/s). These erosion experimentation and X-ray materials characterization methods will improve our fundamental understanding of solid particle erosion, and performance optimization via computational algorithms will allow for rapid prototyping of protective coatings.
 
BIOGRAPHY:
 
Dr. Zherui Martinez-Guo is a Research Assistant Professor with Purdue’s School of Aeronautics & Astronautics and the current head of the Impact Science Laboratory. He holds a courtesy appointment in Materials Engineering and has joint faculty appointments with Argonne and Idaho National Laboratories. He graduated from Purdue University in 2020 with a Ph.D. in Aeronautics and Astronautics Engineering, focusing on the ballistic/hypervelocity impact and performance optimization of protective armor systems. He was a Russell L.Heath Distinguished Fellow with Idaho National Laboratory’s National & Homeland Security directorateprior to coming back to Purdue. His multi-disciplinary research combines experimental efforts in impactdynamics, solid particle erosion, composites science, and advanced materials characterization methods usingsynchrotron X-rays to develop design optimization and materials selection criteria.
