Experiments on adding a surfactant to water drops boiling on a hot surface

The effect of adding a surfactant (sodium dodecyl sulphate) to droplets boiling on a hot stainless steel surface was studied. Experiments were done using solutions containing 100 ppm and 1000 ppm by weight of surfactant and the results compared with those for droplets of pure water. Surface temperat...

Description
Summary:The effect of adding a surfactant (sodium dodecyl sulphate) to droplets boiling on a hot stainless steel surface was studied. Experiments were done using solutions containing 100 ppm and 1000 ppm by weight of surfactant and the results compared with those for droplets of pure water. Surface temperature was varied from 60 to 340 degrees C. Droplet impact and evaporation was photographed using both video and 35 mm cameras.
