Abstract
This work presents an experimental investigation of a water film thickness driven by a turbulent gas flow in a flat minichannel. It was found that the transition from macro- to minichannels can lead to a significant reduction in film thickness at comparable flow parameters. An existing model has been modified to estimate the average thickness of a liquid film under conditions of turbulent gas-driven film flow in a minichannel.
