科研活动

我的研究小组有四名博士生(卢敏、李荣、劳铁涛、柴锦)和三名硕士生(孙俊、童俊淇、李千千),主要从事两相湍流的数值模拟研究,开发了高保真度两相流仿真平台Computational Air-Sea Tank(CAS-Tank)。该平台可以精细捕捉水、气两相界面,例如下图图片中展示的波浪破碎,冲击,射流(李荣制作)等问题的精细模拟

     


CAS-Tank也支持复杂几何体和动物体与流场的相互作用,例如下图中的舰艇绕流(童俊淇制作)、小球入水、波浪过圆柱(劳铁涛制作)的尾流等问题

   


温度、盐度、湿度等问题也可以和速度场耦合求解,例如下面图中展示的波浪破碎时的温度场模拟(卢敏制作)、舰艇在水中航行时引起的内波尾迹(柴锦制作)、水滴在下落时的蒸发(卢敏制作)等问题
