Abstract

Experimental investigation of spreading rate variation of liquid droplet under the conditions of its free-falling on a heated surface has been executed. Effect of surface temperature of flexible copper substrate on spreading rate variation of liquid droplet under the conditions of its free-falling has been studied. It has been found that the curve of liquid drop spreading rate changes exponentially. The spreading rate after time point of 0,002s assumes constant values V = 0.3 ÷ 0.5 m/s and does not depend on the surface temperature. Also it has been found that liquid drop spreading rate does not depend on the surface temperature at temperatures up to 108°C. Continued heating results in an increased liquid drop spreading rate and reaches a maximum values at temperature of 140°C. By heating the surface over 140°C the decreasing of spreading rate is occurred.
