The effect of the tilt angle of the slot channel on water runoff

The paper presents the results of an experimental study of the effect of capillary phenomena on water runoff during snow melting in a slotted channel at an inclination angle from the horizontal of 5o, 10o, 15o and 20o. The description of the model of the slotted channel and the technique of carrying out experiments is given. During the experiments, the features of water runoff were revealed depending on the size of the gap and the angle of inclination of the slotted channel. The dependence of the minimum values of the channel gap on the angle of inclination, at which free flow of water is observed without the influence of capillary forces, is obtained. The results obtained can be used in the development of effective methods for removing frost in plate heat exchangers of refrigeration equipment.
