【 摘 要 】

References(15)Cited-By(13)Experimental studies on the rate of evaporation of a volatile, pendant liquid drop under high ambient temperature conditions (high mass flux) were carried out for the evaporation of water, methanol, n-hexane, n-pentane and carbon tetrachloride drops into dry air. Measurements were made for Rep = 32-328, Sc = 0.60-1.66 and dimensionless driving force B=0.02-1.36. Experimental results for the rate of evaporation of a liquid drop under low ambient temperature conditions showed good agreement with the low-flux equation by Ranz and Marshall and also with previous numerical solutions. Experimental results for rate of evaporation under high ambient temperature conditions showed a systematic deviation from the Ranz-Marshall correlation. Taking into account the effect of high mass flux together with the effect of variable properties, a new correlation equation was proposed which correlated all the experimental data very well.
