Chemical reactions under highly intensive bubble boiling

A fundamentally new method is developed for enhancement of heat transfer under subcooled liquid boiling. The method is based on varying the stability of the “heater-liquid” system depending on the ways of controlling the delivery of heat load. This method is realized most simply for the case where boiling occurs on wire elements heated by electric current. The maximal effect in increasing the stability of bubble boiling is attained by using the stabilizer of integral mean resistance of sensor-heater as the source of electric power. It is experimentally found that very high heat loads (for example, up to $5000$ W/cm$^2$ in the case of water) and the mechanism of their realization activate the liquid and lead to a large number of chemical reactions.
