基于高阶方法的工业大涡模拟进展

众所周知,在达到相同精度的情况下,用高阶方法进行大涡模拟,速度可以比二阶方法快几个数量级.由于具有这种潜力,将这些高阶方法"工业化"并在实际中应用已经取得了很大的进展.在过去的十年中,在工业界,特别是在涡轮机械中,大涡模拟的使用已显著增加,这可能是因为燃气轮机中的雷诺数不是特别高,并且此类模拟对理解关键流动机理具有很大...

Progress in high-order methods for industrial large eddy simulation

It is now well-known that high-order methods can be orders of magnitude faster than 2nd order methods to achieve the same accuracy for scale resolving simulations.Because of that potential,much progress has been made in"industrializing"these high-order methods for real world applications.The use of large eddy simulation in industry especially in turbomachinery has seen a significant increase in the past decade,perhaps because of the relatively low to medium Reynolds numbers in gas-turbines and the high-impact of such simulations in understanding key flow physics.In this article,we review recent pro-gress made in enabling LES using high-order methods in the last decade,and identify the most profitable areas of research in the near future to push LES into the design process.
