Heat transport and temperature distributions in large single drops at low Reynolds numbers: A new experimental technique



A new experimental technique has been developed for study of transport from drops. Large single drops are heated dielectrically while suspended motionless in an unheated continuous phase. Direct measurements of temperature distributions within drops are presented both for circulating drops and for drops in which surface-active materials retard circulation. The results of the measurements will be useful in assessing the validity of the various proposed models.
