部分填充水平旋转圆柱筒内涂层流动的实验研究

Experimental study on the flow of internal coating in partially filled cylindrical cylinder rotating horizontally

通过改变液体的动力黏度、填充体积分数(液体体积与圆柱筒容积之比)、圆柱筒转速等实验参数,对部分填充了粘性液体的圆柱筒在绕其水平对称轴旋转时,圆柱筒内液体自由表面出现的各种现象进行了实验探究和初步定性解释.并作出了当固定液体黏度时转速与填充体积分数的实验相图和固定填充体积分数时转速与黏度的实验相图.

By changing the experimental parameters such as dynamic viscosity,filling volume fraction and rotation speed of cylinder,the experimental research and the simple qualitative explanation of various phenomena of liquid free surface in a cylinder partially filled with viscous liquid rotating around its horizontal symmetrical axis were carried out.The experimental phase diagram of the rotation speed and filling volume fraction was drawn when the viscosity of the liquid was constant,and the experimental phase diagram of the rotation speed and viscosity was drawn when the filling volume fraction was constant.
