Overview Modeling galaxy formation is a multi-scale, multi-physics computational problem that must account for a wide range of astrophysical phenomena, scales, and interactions. These models require cutting-edge numerical simulations using vast computational resources. We have performed state-of-the-art adaptive mesh refinement (AMR) hydrodynamic simulations of galaxy formation and evolution of the intergalactic medium. Project Details Our…
Overview On August 5, 2012, NASA’s Jet Propulsion Laboratory (JPL) captivated the world’s imagination by landing Curiosity, the most sophisticated robotic geologist ever developed, on Mars. Since landing in Gale Crater over 370 Martian days (sols) ago, Curiosity has already completed its primary objective of determining whether conditions on Mars could have been a suitable…
Overview One of the inherent risks involved in testing or operating a rocket engine is the possible release of propellant, leading to an explosion. Potential scenarios may range from a small cloud of fuel vapor expelled from an engine prior to ignition during normal operations, to an accident or launch abort event where a large…
Overview Computational fluid dynamics (CFD) simulations are being used to support the design of NASA’s next-generation space launch vehicles. CFD support includes characterizing aerodynamic performance, providing distributed line loads and pressure signatures on the vehicle for structural analysis, performing stage separation analysis, and predicting the launch environment during the ignition and takeoff. Project Details CFD…

Overview Flexible inhibitors have been used in the solid rocket motors (SRMs) to control the burning of propellant. Vortices generated by the flow of propellant around the flexible inhibitors have been identified as a driving source of instabilities that can lead to thrust oscillation in launch vehicles. Potential coupling between SRM thrust oscillations and structural…
