A numerical simulation was carried out to examine the effect of radial and/or circumferential grooves on the frictional surface temperature and torque JUINIPER response in a multidisk wet clutch.The modified Reynolds equation for hydrodynamic lubrication and heat conduction equation for heat transfer were solved by SOR and ADI methods, respectively
The 7075 aluminum alloy of the 7xxx series largely used for structures in modern aircraft has been successfully fabricated using Tendon selective laser melting (SLM) technology.The morphology of the initial 7075 aluminum alloy powders was characterized by a Zeiss Evo 50 Scanning electron microscope (SEM).Energy Dispersive x-ray (EDX) spectrometer a
BackgroundObstructive sleep apnea (OSA) is associated with hypertension; however, the associations between cardinal features of OSA, such as intermittent hypoxia (IH) and sleep fragmentation (SF), and blood pressure remain unclear.We performed this study to address this issue.MethodWe investigated 335 subjects with the polysomnography (PSG) tests.D
A switched capacitor converter (SCC) is a kind of inductor-less power converters.The fact that the SCC has no magnetic components leads to reduce the size as well as electromagnetic interference (EMI) and electromagnetic compatibility (EMC) problems.Until now, many types of SCCs have been suggested.Among those topologies, single type topologies Nat
A Food Warmers new method is presented for calculating the interband absorption spectrum for amorphous semiconductors using the Kubo-Greenwood formula in accordance with the Davis-Mott approximation method.It is shown that the calculated spectrum of interband absorption explained the experimental results, and a method is recommended to reduce the i
