The experimental measurements of convective heat and mass transfer rates from single evaporating water, methanol and ethanol droplets suspended in a turbulent air flow are considered. This study is a continuation of the work presented by Yearling and Gould (1993). Specifically, this paper considers the effects of Reynolds number, mass transfer number and turbulence intensity of the upstream air on the evaporation rate of liquid droplets. For a turbulence intensity of 5% these measurements show that the Nusselt number increases by up to 30% over that for a laminar flow at the same droplet Reynolds number. At 10% turbulence intensity the Nusselt number increases by up to 50%.
