The modelling of fluid flow and heat transfer under coupled conditions remains a challenging issue particularly for industrial-scale enhanced geothermal systems. This paper proposes a simplified approach to model the coupled hydro-thermal system for hot dry rock geothermal applications. The...

In the present scenario, numerous applications perform on solar energy for cooking, heating and cooling, and power generation, globally. Solar air heaters are one of these applications purposely used for, drying, timber seasoning and space heating. In the present work, a solar air heater (SAH)...

Solar volumetric-receivers have been successfully used in both electricity production and thermochemical applications. This paper studies the applicability of this technology to the production of process heat for high-temperature uses (573–1073 K).

Researches on the nanofluids have been increased very rapidly over the past decade. In spite of some inconsistency in the reported results and insufficient understanding of the mechanism of the heat transfer in nanofluids, it has been emerged as a promising heat transfer fluid. In the...

The continuous growth of population results in more consumption of energy. Moreover, land transport consumes about 35% of the total liquid fuel in most countries. The resulting pollutants cause a tremendous death toll. Hence, it is imperative to enhance the fuel efficiency in transport and...

This paper presents thermo-hydraulic performance comparison of rib roughness under investigation, ‘V-down ribs with gap’ and similar reported rib roughness geometries used in solar air heater duct. The present rib roughness has flow-attack-angle and relative roughness height of 60° and...

An analytical overview of experimental results about the heat transfer capabilities of nanofluids is presented, using widely scattered available information from diverse literature sources. It is shown that, despite the large number of publications available about this issue, only few studies...

The heat transfer analysis of hydrate-bearing sediment involved phase changes is one of the key requirements of gas hydrate exploitation techniques. In this paper, experiments were conducted to examine the heat transfer performance during hydrate formation and dissociation by a thermal method...

Extensive research work on heat transfer in heat pipe using conventional working fluids has been carried out over the past decade. Heat transfer in heat pipes using suspensions of nano meter–sized solid particles in base liquids have been investigated in recent years by various researchers...

Solar energy is one of the most efficient, clean and affordable energy alternatives available today. With the current concerns about global warming and ever increasing energy rates, countries are seriously looking for domestic and industrial usage of solar energy. In the present study, a detail...
