竖直平板间液桥形状的观测与预测模型开发
Visualization and prediction model on shape of liquid bridge
摘要
Abstract
Water bridge can affect the performance of fin-and-tube heat exchanger working under dehumidifying. In order to know the influence of water bridge on heat exchanger, the shape of water bridge needs to be studied. In this research, a visual experiment was used to develop the prediction model of water bridge shape. Based on the visual experiment, the contact line and the contact angles of water bridge were measured, covering various water volumes, solid plate separations and five different solid materials. The prediction model of contact linevia correlated aspect ratio was developed, and the prediction model of contact anglesvia the correlated maximum and minimum contact angles was proposed. The mean deviation of aspect ratio of contact line was 3.4% and that of contact angles was 7.9%.关键词
