Measurement of the Influence of Sheet Cavitation on the Heat Generated in a Closed Loop Pumping System
(2021)
Conference lecture
Restricted access - publisher's policyThe so-called hydrodynamic heat generators are claimed as high efficiency heating devices, avoiding scaling by warming liquids without transfer surface with the help of cavitation effects. However, neither the mechanisms ... -
