Integrated Simulations using Exascale Multiphysics Ensembles 

PSAAP stands for Predictive Science Academic Alliance Program. This is a large research program funded by the US Department of Energy and the National Nuclear Security Administration.

The objective of the INSIEME project under PSAAP III is to exploit Exascale computing systems to predict a complex multi-physics phenomenon with combined innovations in task-based programming, runtime environments, physical models, numerical algorithms, data analysis, learning at scale and uncertainty quantification.

The overarching problem is the prediction of reliability of in-space ignition of cryogenic methane and liquid oxygen propellants in a rocket combustor by using pulsed high-energy lasers. The problem involves a broad set of physical phenomena, including multiphase compressible fluid dynamics, phase change, turbulence, mixing, laser-induced ignition, and combustion.

Stanford University is the primary institution with the University of Colorado Boulder and Purdue University as partners.

This is a large research program funded by US Department of Energy (DoE) through the National Nuclear Security Administration (NNSA).

PSAAP is managed by the NNSA Office of Advanced Simulation and Computing (ASC), in collaboration with Lawrence Livermore National Laboratory, Los Alamos National Laboratory and Sandia National Laboratories.
