With the advances of the latest supercomputer technology, high performance computing (HPC) presented opportunities to develop predictive science and engineering.Closely coupled experiments and simulations of combustion processes have already had a major impact on the efficiency of extant combustion motors, from reciprocating engines to turbines in aerospace and automobile industries.
Under current Edisonian cut-and-try methodology, design cycles and market penetration of new engine technologies simply takes too long. HPC simulations of airframes and jet turbines have reduced reliance on expensive experimental test benches, and increased reliance on fully coupled combustion hydrodynamic and structural mechanics codes, both for high fidelity direct numerical simulations and for reduced order engineering design calculations (Report on Exscale Computing 2010, US Office of Science).
As the United State (US) federal government mandated 80% reduction of greenhouse gas emissions by 2050 and the 25% reduction in petroleum usage by 2020, access to HPC simulations of combustion will have an even bigger impact on the energy industry, since over 85% of the world‘s energy is generated by burning fossil fuel. HPC simulation also helps increase the fraction of power generated by carbon-free power plants that evolve fuels, adding another layer of complexity and further underscoring the need for efficient product development cycles.
CFD modeling and simulation has evolved from the megaflop era of the late 1970s to the present era of petaflop computing. Further advancement of modeling and simulation methodology promises a transformation of the role of the computing technique in science and engineering, turning computing into a true science-based predictive discipline.
ECVT, with its capability of high-speed volumetric imaging with arbitrary shapes of vessel geometries, that generates physical parameters which are to date only available with HPC simulation, helps verifying peta to exascale computing codes, making the simulation results real and reducing significantly the needs of hardware and software investmen costs.
