“…The temperature and pressure of the vapor adjacent to the meniscus are T v and p v . When there are no glass beads present ( Bo → ∞ ), Fukusako et al's (1986) experimental results are consistent with the conventional pool boiling curve discussed in Section 10.2. The heat transfer mode is similar to boiling in a wicked surfaces -discussed in the preceding subsection -except that evaporation on the top of the porous medium does not have much effect on the formation and growth of the vapor bubbles.…”

“…A small, trapped, hemispherical vapor bubble with effective radius R b in the vicinity of the wall-wick interface is shown in Fig. Fukusako et al (1986) conducted an experimental study of the boiling of water, R-11 and R-113 saturated in packed beds of spherical beads with diameters ranging from 1.0 to 16.5 mm. The bubble as well as the liquid adjacent to the wall is at the wall temperature T w .…”

“…In the following, we ex amine the experimental results (Fukusako et al , 1986) that support these two asymptotic behaviors, i.e., Bo > 1, the highpermeability asymptote, and Ba ~ 1, the low-permeability asymptote. Then we discuss the low-permeability asymptote using a one-dimensional model (Sondergeld and Turcotte, 1977;Bau and Torrance, 1982;.…”

The general call is urgent as we face profound issues of productivity and competitiveness that require engineering solutions, among others. The Mechanical Engineering Series is a new series, featuring graduate texts and research monographs, intended to address the need for information in contemporary areas of mechanical engineering.The series is conceived as a comprehensive one that will cover a broad range of concentrations important to mechanical engineering graduate education and research. We are fortunate to have a distinguished roster of consulting editors, each an expert in one of the areas of concentration. The names of the consulting editors are listed on the first page of the volume. PrefaceThis monograph aims at providing, through integration of available theoretical and empirical treatments, the differential conservation equations and the associated constitutive equations required for the analysis of transport in porous media. Although the empirical treatment of fluid flow and heat transfer in porous media is over a century old, only in the last three decades has the transport in these heterogeneous systems been addressed in sufficient detail. So far, single-phase flow and heat transfer in porous media have been treated or at least formulated satisfactorily. But the subject of two-phase flow and the related he at transfer in porous media is still in its infancy. This monograph identifies the pr in ci pIes of transport in porous media, reviews the available rigorous treatments, and whenever possible compares the available predictions, based on these theoretical treatments of various transport mechanisms, with the existing experimental results. The theoretical treatment is based on the local volume-averaging of the momentum and energy equations with the closure conditions necessary for obtaining solutions. While emphasizing abasie understanding of heat transfer in porous media, the monograph does not ignore the need for the predictive tools. Therefore, whenever a rigorous theoretical treatment of a phenomenon is not available, semiempirical and empirical treatments are given.The monograph is divided into two parts: part 1 deals with single-phase flows and part 2...

We report a novel boiling heat transfer (NBHT) in reduced graphene oxide (RGO) suspended in water (RGO colloid) near critical heat flux (CHF), which is traditionally the dangerous limitation of nucleate boiling heat transfer because of heater failure. When the heat flux reaches the maximum value (CHF) in RGO colloid pool boiling, the wall temperature increases gradually and slowly with an almost constant heat flux, contrary to the rapid wall temperature increase found during water pool boiling. The gained time by NBHT would provide the safer margin of the heat transfer and the amazing impact on the thermal system as the first report of graphene application. In addition, the CHF and boiling heat transfer performance also increase. This novel boiling phenomenon can effectively prevent heater failure because of the role played by the self-assembled three-dimensional foam-like graphene network (SFG).
