Effects of Cone Angle and Inlet Blade Angle on Mixed Inflow Turbine Performances

The Effect of Blade Angle and Size on Wind Turbine Performance

PURPOSE We have experienced a major fall in the economy in the recent past. We need something to help boost the economy. Our non-renewable sources of energy are also running out. We desperately are in need of an alternate renewable clean resource for energy. In doing this project, the researcher hopes to find the most efficient combination of blade angle and width on a wind turbine. HYPOTHESIS ...

The Effect of Load Phase Angle on Wind Turbine Blade Fatigue Damage: Preprint

This paper examines the importance of load phase angle variations with respect to fatigue damage. The operating loads on a generic three bladed up-wind 1.5-MW wind turbine blade were analyzed over a range of operating conditions, and an aggregate probability distribution for the actual phase angles between the peak in-plane (lead-lag) and peak out-ofplane (flap) loads was determined. Using a fi...

Effect of Inlet Geometry on the Turbine Blade Tip Region Heat Transfer Coefficient and Effectiveness

An experimental investigation of the local film cooling effectiveness and heat transfer coefficient downstream of a row of elongated holes in a simulated axial turbine blade tip is presented. Film cooling is needed to protect the turbine blade tip region from high heat transfer rates, especially when cooling by convection is insufficient to keep the temperature distribution of the blade within ...

Impact of Blade Angle on Miscanthus Harvesting Energy Requirement

Miscanthus is emerging as a promising feedstock for domestic biofuel production. However, inefficiencies of the machinery that is used for harvesting bioenergy crops such as miscanthus currently prohibit commercial production. The performance of a mower-conditioner used to harvest miscanthus was evaluated, and modifications to the disk head were made to allow the machine to operate more efficie...
