... a single droplet with the drop size distribution. The single droplet heat transfer is analyzed as a combination of the vapor-liquid interfacial resistance, the resistance due to the conduction through the drop itself, the resistance from the coating layer, and the resistance due to the curvature...

... as artificially modifying the boundaries) continues to be the fundamental basis for efforts to resolve many different issues in boiling, spray dynamics and coatings, and two-phase flow heat transfer. It is also clear that enhancement of heat transfer is and will be increasingly critical to both large and small...

.... The significantly higher heat transfer rates achievable with boiling can help keep the temperatures of the structure on an acceptable level. It has been shown in many experimental studies that special surface finish or porous coatings on the heated surfaces can intensify the nucleate boiling process markedly. Most...

...Chen Li; G. P. Peterson To better understand the mechanisms that govern the behavior of pool boiling on horizontal highly conductive microporous coated surfaces, a series of experimental investigations were designed to systematically examine the effects of the geometric dimensions (i.e., coating...

...Ping Tu; Hideo Inaba; Akihiko Horibe; Zhongmin Li; Naoto Haruki An analytical solution to a composite annular fin made of a substrate metallic fin and a coating layer has been carried out. Useful expressions for calculating temperature distribution and fin efficiency have been derived. Comparing...

...Zhenhua Liu; Yuhao Qiu The nucleate boiling heat transfer characteristics of a round water jet impingement in a flat stagnation zone on the superhydrophilic surface were experimentally investigated. The superhydrophilic heat transfer surface was formed by a TiO 2 coating process. The experimental...

... conductance is desired. For this reason, soft, high conductivity, metallic coatings are sometimes applied to contacting surfaces (often metallic) to increase thermal contact conductance. O’Callaghan et al. (1981) as well as Antonetti and Yovanovich (1985, 1988) developed theoretical models for thermal contact...

...C. Tangthieng, Graduate Student; F. B. Cheung, Professor, Fellow ASME,; S. W. Shiah, Chairman, Mem. ASME The process of freeze coating of a binary substance on a chilled moving plate is studied theoretically with special emphasis on the behavior of the two-phase mushy zone. The flow and heat...
