本研究旨在了解大气表层，特别是近地面湍流能量耗散的物理特性。利用12传感器热线探头测量表层速度矢量和速度梯度张量分量的独特能力。根据这些测量结果，可以用条件分析和联合概率密度分析计算湍流耗散率。这些测量可以显著地帮助通过双方程建模和大涡模拟来模拟湍流。
英文摘要
ABSTRACT CTS 95-28845 WALLACE MARYLAND This proposal seeks to understand the physics of turbulent energy dissipation in the atmospheric surface layer, especially near the ground. The unique abilities of a 12-sensor hot-wire probe to measure the velocity vector and the velocity gradient tensor components in the surface layer will be exploited. From these measurements, the turbulent dissipation rate can be calculated using conditional analysis and joint probability density analysis. These measurements can significantly aid in the ability to model turbulence by two-equation modeling and Large Eddy Simulation.
