On June 6, Paul Miles became manager of the CRF’s Engine Combustion Department, which focuses on building the science base needed by industry to develop new generations of high-efficiency, clean engines. He took over the helm from departing manager Dennis Siebers, who recently retired from Sandia National Laboratories. Paul brings a wealth of experience to…
With recent hydrogen fuel cell vehicle market acceleration, cities and neighborhoods where these cars are being sold exhibit a growing need to advance hydrogen fueling system deployments. Understanding and assessing hydrogen-fueling and -storage system risks is a challenging proposition because the necessary scientific information is diffuse and found only in isolated published papers, within research…
Allowing solutions unattainable with direct numerical simulation and offering far greater accuracy than conventional engineering methods, large eddy simulation (LES) is now widely used for studying complex thermophysics in propulsion and power systems. However, because LES demands extremely complex tools, predictive LES has been problematic, leading to sometimes ambiguous results and suboptimal use of expensive…
