development of new technologies and combined with creativity and innovation, plays the fundamental role in developing of any community′s value. thus, in this research the design and production of hydroforming device was introduced. one of the best and most efficient technologies in the world of metal forming is wind turbine blade producing with hydroforming method which seems as an innovative m...

1. Abstract Gas turbine engines for aerospace applications have evolved dramatically over the last 50 years through the constant pursuit for better specific fuel consumption, higher thrust-to-weight ratio, lower noise and emissions all while maintaining reliability and affordability. This paper addresses one facet of this inter-disciplinary optimization problem – optimal design of a turbine bla...

Micro-hydro-electric power is both an efficient and reliable formof clean source of renewable energy. It can be an excellent method of harnessing renewable energy from small rivers and streams. The micro-hydro project designed to be a run -of-river type, because it requires very little or no reservoir in order to power the turbine. The water will run straight through the turbine and back into t...

Clean energy harvesting and usage has gained considerable attention in the last few decades. While the horizontal axis wind turbines have been used extensively, they have certain defects and functional limitations. In the present paper, a novel oscillatory wind turbine is proposed. The conceptual design of the new turbine together with its configuration is explained. Dynamical equations of the ...

This paper deals with main design of wind turbine concerning with structure of wind turbines, option between vertical and horizontal axis wind turbines to optimising count of rotor blades

A design point simulation and adaptation of anindustrial GE LM2500+ gas turbine engine is presented. The design point is chosen when the engine runs steadily at operating point and close to the nominal design condition at 29MW power output. The targeted performance parameters are the fuel flow rate (FF), the compressor exit total pressure (P3), the compressor turbine total exit temperature (T8)...

A comprehensive review of fatigue behavior and fatigue design of heavy section wind turbine castings made of ductile iron EN-GJS-400-18-LT is performed. Common metallurgical defects that are affecting fatigue behavior of this material were studied. Review of different researches on quantitative effect of chunky graphite and micro structure on fatigue behavior of EN-GJS-400-18-LT was perform...

An experimental study of the performance and optimisation of a prototype novel drag-driven vertical axis tidal stream turbine is presented. The drag turbine has several unique advantages, including simple blade design, deployable in shallow waters and potential denser array spacing. Performance optimisation was conducted in the hydraulics flume at Cardiff University (CU), where the turbine reac...

The objective of this research is (1) to design and construct the wind turbine simulator based on the adjustable actual wind speed. (2) To investigate the wind distribution, and (3) tobe applied for testing the power output of the micro-wind turbine in the laboratory. Design and CAD drawing was applied to construct the wind turbine simulator prototype.The 3 phase induction motor with axial fan ...
