The Effect of the Substrate Temperature and the Height of the Mini-Channel on the Evaporation of Liquid Droplet Blown by the Gas Flow

The experimental setup has been designed and fabricated to study the evaporation of liquid droplets, blown by the gas flow in a mini-channel with a height of 6 and 9 mm. Substrates were removable, and the surface temperature of the substrate was maintained at a constant level. The shadow method was the main method of measurement. A series of experiments with a water drop of 100 [mu]l volume settled on a polished stainless substrate were carried out. As a result the dependences for the droplet evaporation rate were obtained in the range of temperatures 25–70 °C and Reynolds numbers of gas 0–2000.
