The corona discharge techniques, which are employed to orient dipoles and built up charges inside functional polymers, can develop important commercial applications of electroactive polymers (EAPs) and electrets for energy storage devices, air filters, electroacoustic and electromechanical transducers. We propose hereby an elective hybrid approach to the point-plane corona modeling in order to obtain...
The PCM shotcrete method using FRP grid, with the properties of high strength, low weight, high workability, strong resistance to corrosion, and little influence on the existing structures, has been used in tunnel maintenance to repair the damaged lining of some aged tunnels. However, the construction cases are still few, and the design routine of this method based on quantitative evaluation on the...
The exhaust gas pipe with three branch pipes of diesel engine is analyzed in the paper. A coupling model of heat transfer between solid and gas is set up, and a heat transfer equation is added into the two dimensional model,. The gas flow filed of exhaust pipe has been simulated numerically with SIMPLE method. The velocities, pressure and temperature are compared. The heat transfer from exhaust pipe...
