Abstract
The crisis of heat transfer in a FC-72 liquid film moving under the action of a gas flow along a smooth or micro-finned heater was experimentally investigated. It is shown that the use of micro-finning leads to an increase in the critical heat flux, since additional washing of the heated surface occurs due to the capillary effect.
