# The emerging role of large eddy simulation in industrial practice: challenges and opportunities

@article{Hutton2009TheER, title={The emerging role of large eddy simulation in industrial practice: challenges and opportunities}, author={Anthony Hutton}, journal={Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences}, year={2009}, volume={367}, pages={2819 - 2826} }

That class of methods for treating turbulence gathered under the banner of large eddy simulation is poised to enter mainstream engineering practice. There is a growing body of evidence that such methods offer a significant stretch in industrial capability over solely Reynolds-averaged Navier–Stokes (RANS)-based modelling. A key enabling development will be the adaptation of innovative processor architectures, resulting from the huge investment in the gaming industry, to engineering analysis…
