International Collaborations
The need to reduce CO2 emissions is global, and the CCMSC is fostering international collaborations in support of its mission to demonstrate exascale computing with V&V/UQ to more rapidly deploy a new technology for providing low cost, low emission electric power generation. We highlight the work of three of our visiting international scholars: Rafi Malik… Read more
One-Dimensional Turbulence Modeling of Coal Combustion
James C. Sutherland, Babak Goshayeshi Overview High-fidelity simulation of turbulent combustion is an expensive endeavor because of the range of length and time scales present and the complexity of the physical phenomena involved (nonlinear coupling between mixing and reaction). LES resolves large length and time scales while modeling unresolved scales. LES… Read more
SpatialOps-Nebo EDSL
James C. Sutherland, Matthew Might & Christopher Earl, Tony Saad Overview Programmers for high-performance scientific computing applications must traditionally be cognizant of numerous issues when… Read more
Visualization Research
Large-scale analysis and visualization is becoming increasingly important as supercomputers and their simulations produce larger and larger data. These large data sizes are pushing the limits of… Read more
Particle Combustion
Particle Reactions Combustion of the coal is at the heart of the boiler. The mass release and the heat release due to coal combustion must be known in both space and time in order to calculate the… Read more
Optical Diagnostics
A number of advanced optical diagnostic techniques are available to provide experimental data on oxy-coal flames to the CCMSC. These data will be compared to the simulation data to check for… Read more
Radiation Modeling with RMCRT
Radiation is the dominant mode of heat transfer in the boiler, with the largest section of the boiler dedicated to capturing the radiant energy generated by the coal and gas reactions. Because the… Read more
Exascale Computing with Uintah
Martin Berzins, Christopher Earl, Qingyu Meng, Matt Might, John Schmidt, James Sutherland, J. Davison de St. Germain, Alan Humphrey Driving Problem The driving problem for the use of Uintah under the… Read more
V-UQ With the BSF
Figure 1: The boiler simulation facility (BSF) is a 15MW pilot scale oxy-coal boiler owned and operated by Alstom. The boiler was designed for characterizing the combustion process and heat transfer… Read more
Large Eddy Simulation
Jeremy Thornock & Ben Isaac Figure 4: LES Simulations of the Alstom T-fired BSF 15MW pilot scale facility. The images and movie in Figures 1 and 2 are taken from experiments run on a single,… Read more
CO2 capture in oxy-combustion
Let's explain how oxy-combustion technology works by Alstom Power. Oxy-combustion consists of burning fossil fuel in a mixture of oxygen, produced in and Air Separation Unit (ASU) and re-circulated… Read more
