Newsletter: UP Scientists Uncover Influence of Reflected Shock Waves on Plasma Behavior

[THIS IS A PRESS RELEASE]

By: Eunice Jean Patron

Scientists around the world have extensively studied the expansion of laser-produced plasma (LPP) and the shock waves it generates in a background gas. However, little attention has been given to how the reflected shock wave—one that bounces back from a surface—affects the expanding plasma, despite its potential impact on LPP behavior.

Dr. Rommil Emperado, Dr. Myles Allen Zosa, and Dr. Wilson Garcia of the University of the Philippines – Diliman College of Science’s National Institute of Physics (UPD-CS NIP), together with Dr. Lean Dasallas of the UPD-CS Materials Science and Engineering Program (MSEP), analyzed the interaction of copper LPP with surrounding gas through the direct simulation Monte Carlo (DSMC) method, which simulates particle behavior using random numbers.
