FORCED CONVECTION COOLIG OF MULTIPLE HEAT SOURCES USING OPEN CELL METAL FOAMS

Forced-convection boiling and critical heat flux from a linear array of discrete heat sources

Forced-convection boiling experiments were performed with FC-72, a 3M Fluorinert, at 1.36 bar on a linear array of nine discrete heat sources simulating microelectronic chips, which were flushmounted in a vertical. rectangular channel. The inlet velocity and liquid subcooling were varied from 13 to 400 cm s’ and 3 to 36”C, respectively. Special design of the experimental apparatus allowed each ...

Open Cell Metal Foams: Measurement and Numerical Modelling of Fluid Flow and Heat Transfer

We herein present results from experimental investigations and new numerical methods for the investigation of fluid flow and heat transfer in cellular solids, in particular open cell metal foams. Results from a custom made test facility contribute to enlarge the public available database of open cell metal foams and serve for the validation of applied commercial and inhouse numerical methods. C...

Heat Transfer Study of Perforated Fin under Forced Convection

Fins are protrusions on a heat transfer surface to augment heat transfer rate from it. The increase in area exposed to convection in case of finned surfaces results in increased heat transfer rate. In this study heat transfer characteristics of a pin fin with perforation is numerically analyzed. A pin fin is fabricated and experiments are done under forced convection conditions. The experimenta...
