A water-based functionalized nanofluid was made by surface functionalizing the ordinary silica nanoparticles. The functionalized nanofluid can keep long-term stability. and no sedimentation was observed. The functionalized nanofluid as the working fluid is applied in a thermosyphon to understand the effect of this special nanofluid on the thermal performance of the thermosyphon. The experiment ...

This paper reports a study on the effect of the heat flux, cooling water flow rate, fill ratio and extra volume on the overall performance of a partially vacuumed <span style="font-size: 10pt; color: #...

Abstract The present study on vertical two-phase closed thermosyphon (TPCT) is aimed to determine the suitable volume-filling ratio, as a function of geometries, heat flux and vapor temperature, in order avoid potential local dryout evaporator section hence maximize performance. In study, droplet entrainment, which caused by internal counter flow during nucleate boiling within falling liquid fi...

The unique characteristic of fast water permeation in laminated graphene oxide (GO) sheets has facilitated the development of ultrathin and ultrafast nanofiltration membranes. Here we report the application of fast water permeation property of immersed GO deposition for enhancing the performance of a GO/water nanofluid charged two-phase closed thermosyphon (TPCT). By benchmarking its performanc...

In order to research the special embankment (thermosyphon embankment) damages and distribution of permafrost under Qinghai–Tibet Highway (QTH) embankment. The section K2952–K2953, which is a typical representative QTH, was chosen for detection in determine sources damages. this study, performance characteristics embankment, active layer, table found ground-penetrating radar (GPR) images were re...
