Microturbine generation system is one of the most promising and a fast growing distributed generation sources. It is used in various applications thanks to high efficiency, quick start and high reliability. Combination of the microturbine and storage system (e.g. battery bank) is desirable selection to satisfy the load requirements under all conditions and hence the battery bank can play an imp...

The paper presents a comprehensive numerical and experimental analysis of the Tesla turbine. turbine rotor had 5 discs with 160 mm in diameter inter-disc gap equal to 0.75 mm. nozzle apparatus consisted 4 diverging nozzles 2.85 height minimal cross-section. investigations were carried out on air subsonic flow regime for three pressure ratios: 1.4, 1.6 1.88. Maximal generated power was 126 W all...

Fabrication by the ‘Laser-LIGA’ process of three-dimensional structures for micro-fluidic devices is investigated. Polymer moulds are formed by projection ablation using an excimer laser operating at 248 nm wavelength. The moulds are replicated by electroforming — as in conventional X-ray LIGA — to produce fixed and freely moving nickel microturbine parts with heights of 150 lm, wall angles of ...

The article presents the results of research on operation a wind microturbine model with an adjustable blade pitch angle. physical basics turbine and methods its optimal control are discussed. measurements carried out for selected geometry possibility adjusting angle presented. tests were resistive load linear characteristic non-linear Li-Po battery. simple MPPT algorithm practical controlling ...

This paper presents an experimentally validated computational study of heat transfer within a compact recuperated Brayton cycle microturbine. Compact microturbine designs are necessary for certain applications, such as solar dish concentrated power systems, to ensure robust rotodynamic behaviour over the wide operating envelope. aims at studying 6 kWe micro gas turbine provide better understand...

In the era of coal power station phase-out, natural gas fired combined cycle will drive energy transition towards sustainable generation. a panorama strong requirement for grid flexibility and non-dispatchable renewable penetration, survival thermal plant is strictly linked with operating successfully in compensating fluctuating production through flexible The Italian case taken as reference, c...
