Wet steam is a common two-phase flow whose mass flow-rate can be measured by V-Cone flowmeter. The mass flow coefficient CD of V-Cone is no longer approximately constant which affects the measuring accuracy subject to the complex flow characteristics of wet steam and discrete droplets. Firstly, five main impact factors for CD of V-Cone were obtained by dimensional analysis, namely, vapor Reynolds...
The elliptical electrode collector has much smaller height comparing to traditional one with same inner surface area. Quadrupole lens which focus high-energy particles very effectively was used on the first electrode of collector to compress the electron beam in one dimension. Based on the simulation, the elliptical electrode collector was manufactured and tested. Experiment results show that the...
