Heat pipes are becoming increasingly popular as passive heat transfer technologies due to
their high efficiency. This paper provides a comprehensive review of the state-of-the-art …

Heat is the most common form of energy either in final or intermediate forms, with the latter
enabling energy conversion to other useful forms. Heat is primarily sourced from fossil fuels …

In this study, the effect of using of titanium dioxide-water (TiO 2/water) nanofluid on the
performance of the flat plate solar collector (FPSC) has been experimentally investigated …

Heat pipes are compact and efficient heat exchangers which are widely used in a large
number of thermal devices. Researchers were attracted towards the application of …

Application of nanofluids as a working fluid can increase the thermal efficiency of heat pipes.
The objective of this comprehensive review is to study the previous works to understand the …

Heat transfer enhancement of a heat pipe using aqueous clinoptilolite nanofluid as the
working fluid under different operating conditions was studied experimentally and …

Coalfield fires provide high-temperature heat storage at relatively shallow depths, their
overburden and upper strata contain immense amounts of thermal energy, which is identical …

One salient feature of the heat pipe system is its superior heat transfer efficiency, which
allows the transfer of significant amount of heat at near-zero temperature difference. In …

In this study, the thermal performance of a two-phase, closed thermosyphon (TPCT) was
investigated experimentally. In the experiments, we used water, ethanol, and ethylene glycol …

To enhance the thermal safety when a station blackout accident occurs, a vertical, straight,
wickless-heat pipe is proposed as a passive residual heat removal system on the nuclear …
