This paper outlines results of a proposed layout light 2-bladed rotor, with driving torque constraint matching the generator design, and shows details pultruded blade – rotor geometry. In comparison 1st baseline design 5 MW VAWT concept this present development provides during standstill operation significant less mass comparable level loading strain in blades junctions between tower. Optimized profile having low weight high stiffness is obtained according to evaluations based on...
Selective laser sintering (SLS) is an additive manufacturing technique that enables the production of customized, complex products. SLS has proven itself a viable prototyping tool and method for noncritical The industry picked up on potential SLS, which raised question whether it possible to produce functional products with reproducible mechanical properties application in critical sectors. Properties parts highly depend applied process settings. Hence, present work examined influence key...
Leading edge erosion of wind turbine blades is causing high maintenance cost and therefore higher levelized energy (LCOE). In order to lower the LCOE design reliable blades, causes rain have be understood. Traditionally, (modified) waterhammer pressure equation used determine contact between liquid droplet (elastic) target. This however independent time, size distance center impact which been identified as important parameters. paper focuses on fundamental mechanisms proposes a numerical...
This study presents a detailed material characterization of pultrusion specific polyurethane resin system. Firstly, the chemical behaviour was characterized by utilizing differential scanning calorimetry. The cure kinetics fitted well to an autocatalytic model with Arrhenius temperature dependency. system did not show any inhibition time. Then, viscosity evolution observed using rheometer. From these measurements, gelation point estimated from criterion cross-over storage and loss modulus...
Although Machine Learning model building has become increasingly accessible due to a plethora of tools, libraries and algorithms being available freely, easy operationalization these models is still problem. It requires considerable expertise in data engineering, software development, cloud DevOps. also planning, agreement, vision how the going be used by business applications once it production, continuously trained on fresh incoming data, when newer would replace an existing model. This...
Pultrusion is a continuous manufacturing process used to produce high strength composite profiles with constant cross section. The mutual interactions between heat transfer, resin flow and cure reaction, variation in the material properties, stress/distortion evolutions strongly affect dynamics together mechanical properties geometrical precision of final product. In present work, pultrusion simulations are performed for unidirectional (UD) graphite/epoxy rod including several processing...
The DeepWind concept has been described previously on challenges and potentials, this new offshore floating technology can offer to the wind industry [1]. paper describes state of art design improvements, simulation results vertical axis turbine concept, which implies a high potential for cost saving. most critical aspects are addressed in proving feasibility, if it be scaled up 20 MW. Applying structural mechanics, generator, floater & mooring system, control system design, rotor using...
AbstractComposite materials, as the name indicates, are composed of different materials that yield superior performance compared to individual components. Pultrusion is one most cost-effective manufacturing techniques for producing fiber-reinforced composites with constant cross-sectional profiles. This obviously makes it more attractive both researchers and practitioners investigate optimum process parameters. Validated computer simulations cost less physical experiments, therefore this...
