The connectivity index chi can be regarded as the sum of bond contributions. In this article, boiling point (bp)-oriented contributions for each kind of bond are obtained by decomposing the connectivity indices into ten connectivity character bases and then doing a linear regression between bps and the bases. From the comparison of bp-oriented contributions with the contributions assigned by ch...

A brief review of recent low gravity boiling research by investigators based in the United States is performed. Topics covered include bubble dynamics, nucleate pool boiling and CHF, transition boiling, boiling of mixtures, electric ˆeld eŠects, acoustic ˆeld eŠects, and ‰ow boiling. Planned research activities and recommendations for future

basic understanding of the process of coolant heat transfer inside an engine is an indispensable prerequisite to devise an infallible cooling strategy. coolant flow and its heat transfer affect the cooling efficiency, thermal load of heated components, and thermal efficiency of a diesel engine. an efficient approach to studying cooling system for diesel engine is a 3d computational fluid dynami...

Boiling heat transfer is a superior heat transfer technology using the latent heat transport with phase-change. However, it has been difficult to employ as a cooling technology for electronics because the unstable transition boiling and film boiling with excessive high temperature are impossible to control. In highly subcooled boiling, the coalescing bubbles formed on the heating surface collap...

Recent research progress in the area of nano/micro scale nucleate boiling is reviewed and an up-to-date summary is provided with a focus on the advances of fundamental boiling physics. This review examines nano/micro scale pool boiling experimental and theoretical/numerical work reported in the open literature. On the experimental side, the topics covered are moving contact line, critical heat ...

Differential sensitivity for the release of PCR-detectable genomic DNA upon boiling in water is reported for 45 Campylobacter jejuni and Campylobacter coli strains isolated in Egypt. All of the strains released PCR-detectable DNA when treated with proteinase K and sodium dodecyl sulfate. When DNA was extracted from these strains by boiling in water, nine (20%) of the strains were PCR negative o...

Banerjee The class of dynamics in pool boiling on a large-size heater is assessed under subcooled pool boiling conditions. Transient surface temperature measurements are obtained using surface micro-machined K-ty...

This thesis consists of an experimental investigation of the effect of surfactants on the boiling curve of water. Via adsorbtion to the boiling surface, surfactants alter the surface energy interaction during bubble formation at nucleation sites. The surfactants initially enhance the heat transfer coefficient at the onset of nucleate boiling due to higher nucleation density and higher bubble de...

We present a modeling approach that enables numerical simulations of a boiling Van der Waals fluid based on the diffuse interface description. A boundary condition is implemented that allows in and out flux of mass at constant external pressure. In addition, a boundary condition for controlled wetting properties of the boiling surface is also proposed. We present isothermal verification cases f...

The present study represents part of an effort in considering the replacement of ethylene-glycol/water mixtures with propyleneglycol/water mixtures for engine cooling in automotive application. Experimental results are presented for the heat transfer coeffic ient under flow boiling conditions for water and mixtures of water with ethylene-glycol and propylene-glycol. The range covered includes t...
