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...

It’s considered that pool boiling heat transfer is closely related to the intermittent behavior of vapor mass and the consumption of macro-layer on the heated surface. Many experiments have been carried out to support the macrolayer evaporation model, however, little has been done in the numerical simulation of boiling heat transfer. This paper reports a method to simulate heat transfer near th...

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 ...

The aim of this paper is to propose f-structure representations of two different types of negation: constituent negation and eventuality negation. In particular, the paper substantiates a suggestion recently made within the PARGRAM community that two binary-valued attributes are needed. We also show that, while the distinction between constituent and eventuality negation is often treated as epi...

Transition of bacteria to cell wall deficient L-forms in response to stress factors has been assumed as a potential mechanism for survival of microbes under unfavorable conditions. In this article, we provide evidence of paradoxal survival through L-form conversion of E. coli high cell density population after lethal treatments (boiling or autoclaving). Light and transmission electron microscop...

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...

In this paper, an experimental study investigating the effect of geometrical shape circular and rectangular pin fins on heat transfer performance boiling phenomenon is presented. A pool experiment in HFE-7100 dielectric working fluid under atmospheric pressure was conducted. Boiling curves coefficients different test cases were plotted to evaluate as well captured images samples. Two quantities...
