Electromagnetic forming (EMF) is a high-speed process with significant potential for manufacturing bipolar plates. However, titanium's low conductivity requires the use of driver sheet in traditional EMF, limiting its formability improvement. This study proposed novel electromagnetic method independent loading magnetic field and current (EMF-ILMFC), enabling separate application force Joule heating. The dynamic deformation behavior ultra-thin titanium was investigated using three different...
Abstract The crystalline behaviors and micromorphology of polymers have a large impact on the physical mechanical properties, especially for polypropylene (PP) composites with toughening effect. In this work, changes content ratio layered double hydroxide (LDH) β‐nucleating agent (CaHA), crystallization PP/ethylene vinyl acetate copolymer (EVA)/LDH ternary are investigated by differential scanning calorimeter (DSC), polarizing optical microscopy (POM), electron (SEM), notched strength...
The diversity gains achievable in the generalised distributed antenna system with cooperative users (GDAS-CU) are considered. A GDAS-CU is comprised of M largely separated access points (APs) at one side link, and N geographically closed user terminals (UTs) other side. UTs collaborating together to enhance performance, where an idealised message sharing among assumed. First, geometry-based network models proposed describe topology a GDAS-CU. mean cross-correlation coefficients signals...
Abstract In order to use polypropylene (PP) more efficiently without destroying its excellent properties, heat treatment after molding is undoubtedly a facile and effective way. this work, the temperature time are used as main treatments for process regulation of PP/ethylene vinyl acetate copolymer/layered double hydroxide (PP/EVA/LDH) composites with β nucleating agent. The toughness, crystallization behaviors, crystal morphologies PP/EVA/LDH investigated by using Izod impact tester, X‐ray...
Abstract Driven by global environmental issues, the development of green building materials has become an immediate focus. In this work, n‐pentane was used as environmentally friendly blowing agent to prepare flame‐retardant rigid polyurethane foam (RPUF) with addition expandable graphite (EG) successfully, and effect content on flame retardancy compressive properties RPUF/EG composites investigated through limit oxygen index (LOI), vertical burning test (UL‐94), scanning electron microscope...
For cooperative communications, the decode-and-forward (DF) protocol can give promising error-rate performance provided that relay node has decoding capability. In this study, authors consider DF cooperation for cellular uplink in which source is equipped with a single antenna, and both destination nodes are multiple antennas. case, analyse exact symbol-error-rate (SER) M-quadrature amplitude modulation (QAM) signals over Nakagami-m fading channels. To avoid cumbersome integral calculation,...
Many studies, experimental, theoretical, and numerical, have been done on polymer nanocomposites, but nearly all of them focused a particular type material system or some specific properties. A comprehensive understanding this complicated is still quite lacking. The objective study to use mesoscale finite element simulation gain insights the reinforcing efficiencies different types carbon nanofillers as distinguished by their geometries interfacial strengths. It demonstrated that CNT (carbon...
The underwater electrical wire explosion (UEWE) is a physical phenomenon initiated by the rapid injection of energy, triggering an explosive event. UEWE offers advantages in energy conversion efficiency, repeatability, and controllability, making it valuable various industrial applications. Building upon established zero-dimensional (0D) one-dimensional (1D) models, this paper proposes enhanced 0D-1D coupled cold-start model to describe plasma channel expansion subsequent shock wave (SW)...
The effect of air resistance on thin-walled sheets cannot be ignored during electromagnetic forming (EMF). More importantly, the magnitude and distribution flow field are difficult to obtain through experimental measurement. To address this issue, a multi-physics simulation model using structured Arbitrary Lagrange Euler (S-ALE) method is constructed. results show that decreases significantly with decreasing ambient pressure. As width workpiece increases, attenuation grows. parameter benefit...
Air change times and differential pressure (DP) gradient are important indicators for measuring the cleanliness of a cleanroom. In traditional dust-free room, control requirements supply air volume (Gs) balance DP usually achieved by adjusting fan frequency angle constant valve or variable valve, which wastes remarkable amounts time money cannot achieve accurate regulation. Therefore, based on analysis cleanroom model, Gs strategy (SAVS) adjustment algorithm (DPGA) were proposed in this...
