hollow cone
1.The spray area of this series of nozzle is formed by one or several continuous hollow cone-shape rings of concentric circles.The nozzle aperture will not be blocked up.It is mainly used for flue elimination,cooling of steel-making convertor.and redistributing in all kinds of washing towers.it also can be used for jar cleaning.used in cooling tower and fire apparatus.
2.Based on the characteristics of hollow wave guide for CO2 laser delivery, a cone-shaped wave guide coupler system was designed and fabricated in this work.
3.This paper does related research on cone beam 3D CT simulation technique: establishes the mathematical model of simulation system using Monte Carlo method; proposes a simulation algorithm based on ray-tracing and on the X-ray attenuation law; develops a simulation prototype software successfully, which is tested and verified by using hollow turbine blade CAD model as phantom object.
