Foam heat exchanger
WebAnother advantage of foam heat exchangers is that all flow paths through foam are interconnected, so that if a flow becomes obstructed by debris lodged in foam at one … WebHowever, at high air velocities, the copper foam exhibited a higher heat transfer coefficient. The Colburn factor was higher for the heat exchanger with copper foam than in the conventional fins, where it was equal to 0.1959 for the copper foam and 0.1186 for the fins. On the other hand, the AG was higher in the case of fins than in the heat ...

WebA heat exchanger is disclosed that includes a cold heat exchange zone including a foam material having an annular geometry and having fluid distribution and collection slots configured to distribute a cooling fluid circumferentially through the foam material. Application Number: 024,101/14: Government Interests: WebProperties. The heat exchanger is modelled as a volumetric energy source where the energy transfer between two fluid streams is based on an effectiveness, specified as a function of the mass flow rates. The energy source …
WebEach metal foam heat exchanger consisted of a two-centimeter diameter pipe with a cryogenic cooler attached perpendicularly to the system. Adjacent to the cryogenic cooler, a metal foam insert was situated inside the pipe, measuring three centimeters in length. The three models of this configuration differed only in the type of foam used as an ... WebThese boiling simulation methods using the OpenFOAM CFD tool are also used to study the cooling properties of high-performance electronic devices. Vontas et al. ( 2024) studied the effect of diameter ranging from 50 µm to 200 µm and the effect of single versus multiple channels on flow boiling.
