Two-Phase Shear Layers and Liquid Sheet in an Airstream in the Compressible Regime

AMS Seminar Series
Zoe Barbeau, Flow Physics and Aeroacoustics Laboratory, Stanford University

This presentation covers the extension of a high-order compact finite difference framework to compressible, two-phase flows for simulation of atomization and the study of temporal two-phase shear layers and liquid sheets in an airstream.

NASA Releases Powerful LAVA Software to US Aerospace Industry

For years, NASA engineers have turned to the NAS-developed Launch, Ascent, and Vehicle Aerodynamics (LAVA) framework to solve airflow challenges that could mean the difference between mission success or failure. When engineers need to know how a spacecraft will navigate re-entry or whether a new aircraft wing design will create enough lift, they turn to LAVA. NASA recently released this tool to the aerospace community. The same computational tools simulating Mars landers, predicting launch environments, and optimizing aircraft for efficiency is now available to U.S. researchers, companies, and innovators.

Find out more about NASA's LAVA software.


Chimera Grid Tools Version 3.0 Released

The Chimera Grid Tools (CGT) team at the NASA Advanced Supercomputing Divison recently released version 3.0 of the industry-standard computational fluid dynamics analysis software package.

CGT was originally released in 1999 and is used in a wide variety of disciplines, including aerospace, marine, automotive, environmental, and sports. It's available for by request through NASA's Software Library.

NASA’s COFFIES Uses AI to Predict Storm-Causing Active Regions on Sun

A novel machine-learning model developed by team of astrophysicists and data scientists is capable of predicting the emergence of active regions on the Sun up to 12 hours before they appear. With the help of NAS supercomputers, the team developed an artificial intelligence approach to analyzing data captured by NASA's Solar Dynamics Observatory to capture subtle, time-based pattern changes on the solar surface before an active region takes shape.
