Advancing understanding of and predictive modeling capabilities for high-speed shock-induced droplet aerobreakup and surface damage
Abstract
The overall objective of this project is to advance fundamental understanding and modeling capabilities for high-speed droplet aerobreakup and surface damage. We will leverage existing capabilities in the NGA2 numerical framework (developed by Prof.~Desjardins, Co-PI) to focus on ONR flight-relevant conditions for high-speed vehicles operating in adverse weather conditions. NGA2 uses a sharp interface method to capture liquid/gas interfaces, while other ongoing research efforts use a diffuse interface method. We expect that using a sharp interface method will affect modeling results for droplet aerobreakup and subsequent impact/damage modeling. Our results will be compared and contrasted to both experimental data and other ongoing numerical efforts in this area, and will be used to update reduced-order droplet drag and breakup models. This work will complement recent DoD-funded programs that have used NGA2 to predict spray formation in gas turbines (ONR) and fuel injection in scramjetengines (AFRL).Cleared for Public Release
