主要研究方向

1．磁-旋转热对流

• 在行星或恒星内部，由导电流体湍流热对流所驱动的磁发电机效应，被认为是天体产生自身磁场的重要机制。然而，受天体自转所产生的巨大科里奥利力的约束（即taylor-proudman效应），天体内部的湍流强度在理论上是不足以产生和维持磁场的。我们通过湍流直接数值模拟研究热对流中洛伦兹力与科里奥利力的相互作用机制，及其二者如何增强热对流和传热，从而促进磁发电机效应的产生。

2．旋转穿透对流

• 湍流热对流是驱动海洋和大气中热量与物质交换的主要机制。通常条件下，流体的密度与温度近似满足线性关系（浮力与温度成反比）。然而在实际应用中，水在温度低于4摄氏度会出现密度反转的情况，形成穿透对流。穿透对流广泛存在于自然界中，为了逼近行星尺度上流动的真实物理条件，我们研究科里奥利力如何对穿透对流系统流动和传热行为产生影响。

3．终极态湍流输运与相干结构

• 自然界中的湍流参数通常处于终极态湍流。实验室尺度的研究很难真实反演自然界中的流动行为。标度律关系是连接实验尺度流动与真实流动之间的重要桥梁；借此关系式，人们可以将实验室获得的结论推广到自然界任意尺度的流动中。本研究以经典湍流系统—taylor-couette流为原型，研究经典态、终极态湍流的角动量与热量输运标度律和湍流相干结构演化。
