Thermal efficiency

TL;DR: In this article, the authors presented an experimental investigation of heat pipe evacuated tube solar collector with and without phase change material for water heating application under the same weather conditions, and the results showed that SA-67 has excellent chemical and thermal stability.

TL;DR: In this article, a novel power generation cycle is presented, which is a combination of the modified Kalina Cycle and the Gas Turbine-Module Helium Reactor system.

TL;DR: In this article, the thermal performance of cascaded heat storage with unsteady inlet temperature of heat transfer fluid (HTF) is analyzed and the optimization of temperatures of HTF and phase change materials (PCMs) is performed based on exergy, entropy, and entransy.

TL;DR: In this article, an adsorption system based on a physical adsorbent i.e. activated carbon is first assessed to capture CO2 emissions from a natural gas combined cycle and then a subcritical sequential supplementary firing combined cycle with CO2 capture is used to analyse the effect of CO2 concentration.

TL;DR: In this paper, two water-in-biodiesel emulsions are tested as pilot fuels during hydrogen dual-fuel operation, while the emulsified biodiesel pilot fuels generally increase thermal efficiencies when compared with the neat pilot fuel during dual fuel operation.
