Liquid-flow rate that corresponds to these regimes is called a minimum wetting rate and the corresponding film thickness is called a minimum film thickness [1].
Results of experimental investigation for this liquid-plate material combination showed that minimum wetting rate, area of dry surface and mass transfer coefficient changes abruptly in the case of the brake-up while the counter-current air flow is introduced.
Contact angle is in correlation with the minimum wetting rate as follows: a receding contact angle for the breakup of a continuous liquid film and advancing contact angle for wetting of a previously dry surface.
