FIELD: physics.
SUBSTANCE: invention relates to the field of development of methods and devices for laboratory research of physical processes, in particular for investigation of laws of liquid drops evaporation at heating with external heat flow. Device includes an ultrasonic levitator fixing a drop in the acoustic field of the resonator, a droplet heating system with an external heat flow and a visualization system. Droplet heating system includes a xenon lamp with adjustable power placed in the parabolic reflector focus. Visualization system includes two video cameras arranged to record the shape and size of the drop in perpendicular planes, and at the point of drop localization a movable sensor of radiant heat flow is installed with possibility of its removal before measurements. Rate of evaporation of droplets is determined from algebraic ratio as per measured droplet sizes.
EFFECT: high accuracy of determining droplet evaporation rate.
