Reciprocating compressors are critical components in the oil and gas sector, though their maintenance cost is known to be relatively high. Compressor valves are the weakest component, being the most frequent failure mode, ...

A new concept in aircraft propulsion is described in this work. In particular, variable jet engine is investigated for supersonic ASTOVL aircraft. This engine is a Selective Bleed Variable Cycle, twin shaft turbofan. At ...

Military aircraft are often subjected to severe flight maneuvers with high angles of attack and angles of sideslip. These flight attitudes induce non-uniformity in flow conditions to their gas turbine engines, which may ...

The main aim of this work is to investigate variable cycle concept for combat aircraft with super cruise capability. In particular, this study investigates impact of different variable geometry mechanisms and components ...

The global resources of unconventional oil such as heavy oil, extra-heavy oil, and bitumen are vast and are expected to play an increasingly important role in meeting the world‘s future energy needs. However, the highly ...

This study presents a novel design and development of a 280,000 m3 liquefied hydrogen tanker ship by implementing a set of 6 Flettner rotors as an assistance propulsion system in conjunction with a combined-cycle gas turbine ...

Among the major deterioration problems a gas turbine encountered while in operation is compressor blade fouling. This is the accumulation and adhesion of dirt and sediment on the compressor blade which contributes between ...

With renewed interest in research and development on the closed-cycle gas turbine technology, it is almost certain this energy conversion system may well emerge in the foreseeable future as a viable option in power generation ...

A tool based on a Techno-economic and Environmental Risk Assessment (TERA) framework is useful at the preliminary stage of an aero engine design process, to conceive and assess engines with minimum environmental impact ...

This research examined the technical and economic feasibility of harnessing flare gas emissions from oil fields. The outcome would provide the basis for a substantial re-utilization of this waste energy due to the current ...
