Simulation and I/O Scaling for An Integrated Multi-physics Code

Usage Details

XPACC seeks to advance engineering of plasmas to access mechanisms unavailable in traditional combustion in order to boost performance and eÿciency. Radicals produced directly in plasmas can short-circuit standard chemical reaction pathways; electric fields a˙ect flame stability; and plasma Joule heating a˙ects both flow and chemistry. In designing these simulations and assessing their predictive capacity, an Uncertainty Quantification framework is designed to integrate the predictive large-scale simulations with low-dimensional, physics-targeted configurations designed to identify relevant mechanisms and calibrate models. These same mechanisms and models are integrated for the principal demonstration simulations: the prediction of the sustained ignition threshold of a fuel jet in a turbulent crossflow.
