LEADING ENGINEERING SIMULATION CONFERENCE
High performance computing design exploration for a 500 MW oxy-coal fired boiler using STAR-CCM+ and OPTIMATE+
The mission of the Carbon-Capture Multidisciplinary Simulation Center (CCMSC) at the University of Utah, a five-year $21M Department of Energy funded program, is to demonstrate the use of exascale uncertainty quantification (UQ) predictive simulation science to accelerate deployment of low-cost, low-emission electric power generation to meet the growing energy needs in the United States and throughout the world. The two main objectives, advancing simulation science to exascale with UQ-predictivity in real engineering systems and use of high-performance computing (HPC) and predictive science to achieve a societal impact, are linked together through an overarching problem: simulation of a design 500 MW oxy-coal advanced ultra-supercritical (AUSC) horizontal boiler. The simulation of oxy-coal AUSC horizontal boiler is motivated by the emergence of oxy-combustion systems as a low-cost technology solution for both carbon capture utilization and storage and simultaneous reduction of NOx and SOx emissions. By partnering with N.S. Harding and Associates, an industrial boiler design firm with two decades of industrial experience, we explore a range of scenarios and designs to predict and quantify heat flux distribution inside the design boiler, aiding in material science research of steam tubes that are able to withstand the high temperatures and pressures of oxy-fired AUSC systems. STAR-CCM+® plays an integral part of our workflow because of its capabilities to resolve complex geometries and being able to take advantage of high performance computing platforms, allowing us to run simulations with hundreds of millions computational cells on as many as 4,000 cores with excellent scaling. Coupled with OPTIMATE+, we are able to perform design exploration study to explore the effect of boiler features, components and firing conditions on the heat distribution inside the 500 MW horizontal oxy-coal fired boiler.
