Effets thermiques dans la cavitation des fluides cryogéniques
Thermal effects in the cavitation of cryogenic fluids
Groupe Phénomènes d'Interface Ecole Nationale Supérieure de Techniques Avancées Palaiseau, France
The vapour production required to sustain a cavity leads to a temperature reduction at the interface. This temperature reduction, though quite small in the case of water, is significant in the case of cryogenic fluids. A method assuming that (i) the vapor production is equal to the volume flow rate of air required to sustain a ventilated cavity and (ii) that heat transfer at the interface is analogous to that over a rough flat plate, gives reasonable estimates of the temperature reduction.
