In this paper, we used a homogenization method to estimate the equivalent properties of composite material, which depend on a microstructure and behavior of constituents (fiber and matrix). The estimated results conform well to the results of the rule of mixtures, which is a conventional method...

In this study, we designed a biomass popping pretreatment, system using a fired burner and a horizontal cylinder rotating on an axis, to produce ethanol from mandarin (Citrus unshiu) peel (MP) waste. Popping pretreatment was performed at 150°C for 10min without chemical treatment. Popping...

Wind turbine blade is made of multilayer composite materials, which is exposed to various temperature changing environmental conditions like snowing, icing, and heating from visible and ultraviolet ray. This can make stress and strain for all life time continuously. Therefore the stress–strain...

Recent interest in Darrieus wind turbines has led to a need for proper performance prediction models. Of all the existing models, multiple streamtubes model is reasonably simple and relatively precise. However, neglecting dependency of Reynolds number (Re) leads to the failure of prediction at...
