Thin liquid film flow rising along the outer surface of the cone is generated when the cone rotates, which is immersed in the liquid by turning the top upside down. The film flow becomes thinner as going upward, which leads to atomization of the liquid. We aim to clarify the rising mechanism of the film flow and the subsequent atomization characteristics.We measured the film thickness using an ultrasonic distance measuring sensor to make clear the rising mechanism and obtained the correlation between the film thickness and the rotation rate. In addition, it is important to know the power consumption necessary for the generation of mist flow and rising film flow along the rotating conical outer surface. We measured the torque acting on the rotating cone by using the torque sensor. The values of torque depend on the mist flow quantity. So, we clarified the relationship between the mist flow quantity and power consumption necessary to pump up the liquid film flow and make the mist flow.

锥体旋转时，产生沿锥体外表面上升的薄液膜流，通过将顶部倒置而浸入液体中。膜流随着向上而变细，从而导致液体雾化。我们的目的是阐明膜流的上升机制以及随后的雾化特性。我们使用超声波测距传感器测量膜厚，以明确上升机制，并获得膜厚与旋转速率之间的相关性。此外，了解沿旋转圆锥形外表面产生雾流和升膜流所需的功耗也很重要。我们使用扭矩传感器测量了作用在旋转锥体上的扭矩。扭矩值取决于雾流量。因此，我们明确了雾气流量与泵起液膜流量并使雾气流动所需的电力消耗之间的关系。
