Insight into Damping Sources in Turbines

چکیده

Abstract Blade vibrations in aircraft engines are a significant challenge that must be overcome during the design and development of modern turbine engines. Vibrations lead to cyclic displacements result alternating stress strain undesired environments (high temperatures, erosion, corrosion surface, etc.). Under resonance conditions, amplitudes can increase exceed their safety limits, extreme cases, engine failure. One method reduce is damping assembly. This paper presents describes vibration sources turbine, including aerodynamic, material, friction damping. Additionally, typical values for each component presented compared.

New Insight into the Relation between Adiponectin and Diabetes

Diabetes mellitus is a group of metabolic diseases. Insulin resistance is defined as a state that needs more insulin to get the biological effects achieved by a lower amount of insulin in the normal state. Several molecules which are secreted through adipocytes have been involved in insulin resistance and type 2 diabetes mellitus. Adiponectin as a 244 amino acid protein is exclusively expressed...

Determination of significant sources generating low-frequency noise in horizontal axis wind turbines

Several studies show that the Low-Frequency Noise (LFN) of wind turbines could have harmful effects on human health even when it is infrasound. In traditional classifications, the LFN of upwind turbines is referred only to steady thickness and steady loading sources, and the effect of vortices is considered negligible. In this study, the LFN of a horizontal axis wind turbine is simulated in win...

New insight into superconductivity

NOVEMBER 2008 | VOLUME 11 | NUMBER 11 13 The physics of high-temperature cuprate superconductors in the overdoped regime, where superconductivity is suppressed, is something of a mystery. But first-principle calculations by researchers in the US and Switzerland appear to confirm a recent suggestion that ferromagnetism can destroy superconductivity at high doping levels [B. Barbiellini and T. Ja...
