Abstract
The capabilities of flow visualization and gradient heatmetry are combined for the first time in studying heat transfer during condensation. The local heat flux per unit area during drop-stream condensation of water steam on the surface of a vertical plate was measured. In the drop-stream condensation mode, the average value of a significantly unsteady heat flux was about 31.2 kW/m2. The heat flux unsteady shows a complex physical picture of condensation. The results of the experiment revealed the possibility of using gradient heatmetry as a method for monitoring heat transfer during condensation.
