Prediction of bubble departure in forced convection boiling: A mechanistic

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...

Forced Convection Subcooled Boiling of Binary Mixtures

A mode based on an additive mechanism of heat transfer is proposed for forced convection subcooled boiling of binary mixtures. The contributing modes of heat transfer are: (i) the heat transferred as latent heat by the rising bubbles, (ii) the heat transferred as the heat contained in the superheated thermal layer that is removed from the surface in the wake of the rising bubbles and (iii) the ...

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 ...

An Experimental Study of Heat Transfer During Forced Air Convection

Cast aluminum alloys are usually subject to solution treatment, quenching, and aging hardening for improved mechanical properties. Cooling rate during quenching plays an important role in residual stress, distortion, and mechanical property distributions in the resultant cast aluminum components. As the cooling rates of work pieces heavily depend on the interfacial heat transfer coefficient (HT...
