科研活动

我的研究小组有两名博士后,两名博士生,三名联合培养博士生,三名硕士生,一名联合培养硕士生,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、射流、气泡湍流等问题的精细模拟

         


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、圆柱尾流、螺旋桨尾流引起的破碎波等问题

       


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、舰艇在水中航行时引起的内波尾迹、水滴在下落时的蒸发等问题
