Under a Presidential Young Investigator Award, research will be conducted on compressible turbulent flows and on related issues in acoustics. Both direct numerical simulations and theoretical analysis will be utilized. Compressibility effects on various scales of motion in the turbulence field, on the cascade of energy between scales, and on energy dissipation at the small scales will be studied. Engineering model for more accurate prediction of compressible flows will be developed for application to various high speed and combustion flow system.

在总统青年研究员奖下，将对可压缩湍流和声学中的相关问题进行研究。采用直接数值模拟和理论分析相结合的方法。文中将研究可压缩性对湍流场中不同尺度运动的影响，对尺度间能量级联的影响，以及对小尺度能量耗散的影响。为了更准确地预测可压缩流动，将开发适用于各种高速和燃烧流动系统的工程模型。
