Numerical Simulation of Bank and Center Discharge(CD) of the Meandering Channel; Study of Reduction of GHG Emission from Ships by Shore Power 河流连续弯道处岸边和中心排污的数值模拟船舶使用岸电对温室气体排放的控制研究
We analyze the mechanism of the coupling effect by measuring the plasma density and electron temperature in the center of the discharge space. The electrode spacing, pressure and high and low frequency combination have contribution to the coupling effect. 通过对腔室中心点的等离子体密度和电子温度的测量,分析了放电间距、气压和高低频频率组合等对耦合效应的影响。
Because of the distinct reducing of the swirl velocity and the instability of the forced vortex itself, the vortex at the volute discharge section breaks down easily, inducing the reverse flow at the center of volute discharge section. 在蜗壳出口直管段由于涡流速度明显减小和旋涡自身的不稳定,在小流量下容易发生破裂,导致蜗壳出口的截面中心区域通流速度均出现逆流,此逆流为压缩机失速特征的表现。
The center control computer observes the tidal discharge by sending orders to the water lever and velocity instruments through the optical fiber cable automatically. 中心控制计算机通过光缆向水位和流速仪器发送控制指令并进行监测,实现对潮流量自动监测。
Tested by the Environmental Testing Center of Shaanxi Province, the discharge density of smoke is lower than 20mg / m3, which is lower than the request of new discharge standard. 经陕西省环境监测中心监测,排放浓度小于20mg/m~3。
