【期刊论文】A Method for Removal of CO from Exhaust Gas Using Pulsed Corona Discharge
李晓红, Xiaohong U, Lin Yang, Yuyong Lei, Jiansheng Wang, and Yiyu Lu
ISSN 1047-3289 J. Air & Waste Manage. Assoc. 50: 1734-1738,-0001,():

An experimental study of the oxidation of CO in exhaust gas from a motorcycle has been carried out using plasma chemical reactions in a pulsed corona discharge. In the process, some main parameters, such as the initial CO concentration, amplitude and frequency of pulses, resi-dence time, reactor volume, and relative humidity (RH), as well as their effects on CO removal characteristics, were investigated. O3, which is beneficial to reducing CO, was produced during CO removal. When the exhaust gas was at ambient temperature, more than 8O% CO removal ef-ficiency was realized at an initial concentration of 288 ppm in a suitable range of the parameters.

A new CNC (Computerized Numerical Control) controlled water-cutter system was constructed and an experimental study on the machining of natural rock materials by using this system was conducted. The system has many advantages, such as long available stand-off distance, low specific energy consumption, high cutting efficiency, low pump pressure, low cost, and long life-span to machine various natural rock materials rock materials to any 2-dimentional curves, which are difficult or impossible to machine by using other traditional tools.

The system has many advantages, such as long available stand-off distance, low specific energy consumption, high cutting efficiency, low pump pressure, low cost, and long life-span of nozzle as well as convenient interactive manipulation. The water-cutter system can be widely used to machine various natural rock materials to any 2-dimentional curves, which are difficult or impossible to machine by using other traditional tools.

【期刊论文】The optimal jet position when water jet assisted drag bit cutting rock
李晓红, X. Li, and M. Hood
,-0001,():
-1年11月30日
The jet position has a important influence on cutting process when water jet assists bit cutting rocks. In this paper the test for the effect of jet position on drag bit cutting process is described. The experimental methods, instrumentation and procedure are conducted. Four different jet positions were investigated in the test. The range of diameter of nozzles used is from 0.5 mm to 1.0 mm. The influence of jet position on rock chips formed ahead of bit is discussed. The effect of cut depth, bit velocity on bit force reductions is analyzed. The effectiveness of jet energy is examined for all kind of jet positions. And some important conclusions are given in the end of this paper. One of the most interesting results is that the water jet has the largest effect on drag bit cutting process when it is directed towards the center beneath the bit.

In this part of the paper, the test that three PDC drag bits with different rake angle were used to make linear cuts in two rock types is conducted. The experimental methods, instrumentations and process are described. In order to investigate the relationship between the wear and damage of PDC inserts and bit forces as well as the influence of moderate pressure water jets on the cutting process is analyzed. Towards the end of this part of the paper, the conclusion is given.
