Aero-engines and rocket engines regularly experience unstable combustion phenomena. In order to reveal the complex mechanism, it is necessary measure jet gas–liquid interface disturbances. However, most techniques require optical access measurement fails when limited. Ultrasonic method can be considered as an alternative under this condition. The present work proposes acoustic approach for measuring based on ultrasonic scattering. A thorough investigation of scattered field by conducted...
Cross-linked polyethylene (XLPE) plays a significant role in AC power cables. In the cables, difference temperatures of conductor and surrounding environment produces temperature gradient XLPE, electrical thermal aging accelerate degradation. When defects exist dielectric, an tree may be initiated. Hence, it is necessary to research XLPE under gradient. this paper, samples were tested 50 Hz voltage with multiple gradients, was recorded by digital microscope. To simulate stress concentration,...
In this paper, a compact input-reflectionless balun with low phase/amplitude imbalance based on stacked-coupled microstrip line is proposed, which consists of reflectionless- and balun-sections. The reflectionless-section particular two-stage coupled transformation structure. absorbing resistor located at the end 90 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">°</sup> line, can introduce theoretically ideal all-band reflectionless...
