论文摘要
在这项研究中，我们探索了几个积分和外部长度尺度，可以通过使用温度波动（$χ$）和其他相关变量来制定这些湍流。我们的分析直接导致$χ$和温度的结构参数（$ c_t^2 $）的简单但非平凡的参数化。出于我们的目的，我们利用了分层通道流的直接数值模拟的高保真数据。
In this study, we explore several integral and outer length scales of turbulence which can be formulated by using the dissipation of temperature fluctuations ($χ$) and other relevant variables. Our analyses directly lead to simple yet non-trivial parameterizations for both $χ$ and the structure parameter of temperature ($C_T^2$). For our purposes, we make use of high-fidelity data from direct numerical simulations of stratified channel flows.
