The investigation of the various heat management concepts using LH2 requires development a modeling environment coupling cryogenic hydrogen fuel system with turbofan performance. This paper presents numerical framework to model hydrogen-fueled gas turbine engines dedicated heat-management system, complemented by an introductory analysis impact precool and intercool in compression system. propul...

Population growth, technological advancements, and growing living standards have all contributed to a rise in energy demand. Due the fact that fossil fuels are not sustainable, renewable sources emerged as viable alternative. The need for development is time. In this study, combined cycle power plant which solar integrated discussed. For purpose, designed model calculations; data, values of Emi...

The bias-extension test is one of the methods to characterise intra-ply shear behaviour continuous fibre reinforced composites including fabrics and unidirectional (UD) materials. For determination major mechanical properties metals, often a uniaxial tensile used. Combination these two for deformation hybrid metal-composite laminates proposed comparing method cross-plied prepregs woven fabric p...

Abstract Cold Spray (CS) exhibit unique features due to the low temperatures involved. However, CS coating are harder than corresponding powders and bulk alloys, which results in a toughness then greatly limits application of CS. To overcome this shortage, preheat treatment powder post-heat applied improve performance cold-sprayed 7075 aluminum alloy coatings work. With increasing treatment, te...

The structure of premixed turbulent flames and governing physical mechanisms the influence turbulence on burning are often discussed by invoking combustion regime diagrams. In majority such diagrams, boundaries three regimes associated with (i) flame preheat zones broadened locally eddies, (ii) reaction (iii) local extinction based a Karlovitz number Ka, differently defined Ka being used to dem...

The weather in the high latitudes of China is cold winter. pollution caused by burning biomass fuels used rural individual heating a great threat to human health. This study finds that amounts CO2, CO, PM2.5, and PM10 bedroom exceed standard temperature does not meet based on indoor air measurements residential buildings Liaoning Province In this study, mechanical ventilation method which uses ...

A statistical analysis is conducted for turbulent hydrogen-air premixed flames at a range of Karlovitz numbers up to 1,126 by direct numerical simulations (DNS) with detailed chemistry. The local and global burning velocities are evaluated the deviation from laminar flame speed assessed. It found that largely determined integral length scale than number, due surface area enhancement. in all exa...

This work proposes an innovative method for adjusting the natural gas from grid to consumer pipeline requirements in a full-scale pressure reduction station. The use of two counterflow vortex tubes instead traditional boiler preheat before throttling is demonstrated as powerful alternative. Thus, fossil fuel consumption reached, which amounts 7.1% less CO2 emitted. To ensure optimal configurati...

One of the most significant issues that need addressing is lack clean and fresh water. There no substitute for water, there a growing innovative modern desalination systems design solar-driven desalination. A normal solar system consists tank, glass plate to cover tank and, small reservoir collect it. We will incorporate additional setups into our improve performance standard traditional system...
