  • Arrester - an overview | ScienceDirect Topics
    An arrester can be considered a replica of an HRC fuse While a fuse is a current limiting device and protects the connected equipment by limiting the prospective peak fault currents, ISC (Figure 12 18) an arrester is a voltage limiting device and protects the connected equipment by limiting the prospective peak surge voltage, Vt (curve 3, Figure 17 21)
  • Effects of flame arrester on H2-Air detonation under different initial . . .
    The flame arrester cavity has a different cross-sectional area than the pipe, leading to a diffraction process of the shock wave within the cavity that impacts the propagation of the combustion wave This aspect is seldom highlighted in studies analyzing the quenching of deflagration waves
  • Experimental study on the quenching effect of copper foam flame . . .
    Therefore, it has broad application prospects in porous media-based thermal management systems A flame arrester structure based on copper foam is proposed in this study, aiming to achieve efficient energy absorption and fast quenching of high-temperature jet flames by utilizing its high specific surface area and excellent thermal conductivity
