Abstract: A bench for studying heat exchange between a pulsed spray and a surface heated to a temperature below the boiling point is designed. A calorimeter to measure the integral heat exchange accurate to 1.5–3.0% and equipment generating the pulse spray are described. The main parameters of the forming gas-drop-let flow (the gas and liquid velocities, the variation of the hydropulse duration and the size of flow-constituting droplets when moving toward a heat exchanger, and the liquid concentration distribution over the cross section and along the flow) and respective measuring techniques are given. It is shown that the duration of a droplet train in the flow influences heat-and-mass transfer.
