The Carbon-Capture Multidisciplinary Simulation Center (CCMSC) is demonstrating exascale computing with V&V/UQ to more rapidly deploy a new technology for providing low cost, low emission electric power generation to meet the growing energy needs of the U.S. We are using a hierarchal validation approach to obtain simultaneous consistency between a set of selected experiments at different scales embodying the key physics components (large eddy simulations, multiphase flow, particle combustion and radiation) to predict performance in a 350MWe oxy-fired boiler. To solve this problem, we are developing the following tools:
The CCMSC is funded by the Predictive Science Academic Alliance Program.
Predictive Science Exascale Computing and Software V&V/UQ ![]() 1. turbulent fluid transport, 2. multiphase flow, 3. particle combustion, and 4. radiative heat transfer. Advances in these four areas will provide predictions of a wider range of phenomena, over a wider range of space and time scales, with improved predictive accuracy and reduced uncertainty, or at least a better understanding of the uncertainty in comparison to existing capabilities.We anticipate the majority of the disciplinary advances will come as a result of the tight coupling between the predictive science team with the exascale and V/UQ activities.
![]() 1. the exascale runtime system, 2. TASC (Transparent Abstractions for Scalable Computing) representing a high-level, portable "assembly language" for scientific computation with transparent abstraction by using a sub-Turing, embedded domain-specific language, and 3. the data management and visualization infrastructure for dealing with large data and for connecting that data to the visualization and data analysis components.
