在这个更新的建议中,PI建议继续他的湍流研究,特别是在大涡模拟(LES)建模方面。 为了获得精确的LES模拟,需要知道动量的小尺度、亚网格尺度以及标量(如温度和浓度)的输运。 在本计划中,PI将集中研究湍流中的被动标量动力学,将对加热圆柱尾迹、加热射流和具有温度梯度的网格湍流进行实验,以获得这些流动中的亚网格尺度热量和动量输运。 实验结果将用于制定适当的SGS模型应用于LES。
英文摘要
AbstractIn this renewal proposal, the PI proposes to continue his investigation of turbulent flow especially in terms of Large Eddy Simulation (LES) modeling. In order to obtain accurate LES modeling, transport in the small scales, sub-grid scale, of momentum as well as scalar quantities such as temperature and concentration need to be known. In this proposal, the PI will concentrate on the study of passive scalar dynamics in turbulence.Experiments will be performed on heated cylinder wake, heated jet, and grid turbulence with temperature gradient to obtain the sub-grid scale transport of heat and momentum in these flows. Results of the experiments will used to formulate appropriate SGS modeling for application in LES.
