Miniature heat pipe (MHP) with woven-wired wick was used to cool the CPU of a notebook PC. The pipe with circular cross-section was pressed and bent for packaging the MHP on the very limited space of a notebook PC. A cross-sectional area of the pipe is reduced about 30% when the MHP with 4mm diameter is pressed to 2mm thickness. In this study, a performance test has been performed in order to r...

An adaptive Helmholtz resonator was designed and adapted to hydraulics. The resonator was controlled by openand closed-loop controls so that 20 dB attenuation of the peak-to-peak value of the pulsating pressure was maintained. The closed-loop control was noted to be better, albeit it was slower because of its low pressure and temperature variation, which caused variation in the effective bulk m...

We would like to thank Kim et al. for appreciating the importance of our work [1]. It should be noted that the introduction of a disk shaped heat pipe by us in the cited paper was done for the very first time in the literature and our comprehensive analytical results for the disk-shaped and rectangular-shaped heat pipes constitute the very first such analysis in the literature. In summary, we a...

The temperature distribution across a flat heat pipe sandwich structure, subjected to an intense localized thermal flux has been investigated both experimentally and computationally. The aluminum sandwich structure consisted of a pair of aluminum alloy face sheets, a truncated square honeycomb (cruciform) core, a nickel metal foam wick and distilled water as the working fluid. Heat was applied ...

A two fluid model (TFM) was used to study gas-solid heat transfer in a riser with different inclination angles. A two dimensional pipe with 5.8 cm internal diameter and 5 meter length was chosen.  Effect of bed angle and solid particles feed rate were studied on the heat transfer behavior of gas and solid particles. Obtained results from simulation are compared with the experimental data in the...

The turbulent pulsating flow and heat transfer in straight 90° curved square pipes are investigated this study. Both experimental temperature field measurements at the cross-sections of conjugate (CHT) simulation were performed. steady was compared to under same time-averaged Reynolds number. number flow, as well approximately 60,000. Womersley 43.1, corresponding a 30 Hz frequency. Meanwhile, ...

The Photovoltaic/thermal (PV/T) system combines the conventional PV panel with solar collector into one integrated system, which could achieve function of generating power and providing thermal energy at same time. Recently, it has become most promising for building applications. Most PV/T systems use water as coolant, cause freezing problem in winter. To overcome this problem, heat pipe is dev...
