Study of the turbulent mixing zone induced by the Richtmyer-Meshkov instability using Laser Doppler Velocimetry and Schlieren visualizations [PDF]
, 2012 An experimental study of the compressible mixing generated by the Richtmyer-Meshkov instability (RMI) is carried out in a vertical shock tube by means of two-components Laser Doppler Velocimetry (2C-LDV) measurements and Time-resolved Schlieren ...

Gaoya dianqi, 2014 由于SF6气体的温室效应,减少SF6气体的使用具有深远的社会意义,用SF6/N2混合气体取代纯SF6气体作为高压电器设备的绝缘介质是减少使用SF6气体的有效措施。介绍了SF6/N2混合气体的优点。从气体放电理论出发,对不同比例SF6/N2混合气体的绝缘性能进行了分析,结果表明:SF6体积分数仅为20%的SF6/N2混合气体击穿强度为相同气体压力纯SF6的70%左右;若SF6体积分数为20%的SF6/N2混合气体的击穿强度要达到纯SF6气体的击穿强度,其总压力应为纯SF6气体的1.4倍 ...

Negative ion Time Projection Chamber operation with SF$_{6}$ at nearly atmospheric pressure
, 2017 We present measurements of drift velocities and mobilities of some innovative negative ion gas mixtures at nearly atmospheric pressure based on SF$_{6}$ as electronegative capture agent and of pure SF$_{6}$ at various pressures, performed with the NITEC ...
