Liquid gas ejector uses liquid as the motive fluid and gas as the entrained fluid. The presence of gas in the liquid reduces the performance of the ejector, especially the diffuser. To observe the effect of entrained gas on the diffuser performance, a series of experiment was conducted.In this research, the motive flow rate was varied from 1.52 to 2.02 l/s and the entrained rate from 0.118 l/s to 0.944 l/s. Its effects on the pressure profile and pressure recovery were observed. If the entrained rate increase, the pressure of the throat upstream, as well as downstream, increase. In the diffuser, longer distance is needed for the pressure to reach its final value. Pressure recovery is mainly affected by void fraction. The higher the void fraction the lower the pressure recovery coefficient

Contaminant Flow

<p>Electrical failure due to surface discharge on the insulation material will cause material degradation and eventually lead to system failure. The flow of leakage current (LC) on the insulator surface under wet contamination is used to determine the material degradation level. According to IEC 60587 standard, LC exceeding 60 mA for more than two seconds is considered as failure. In this study, the  electric field and current density distributions on the linear low-density polyethylene (LLDPE) and natural rubber blend material have been analyzed using finite element method (FEM) analysis. The physical parameters used in FEM simulation were applied with voltage and contaminant flow rate, in accordance to contaminant conductivity. Tracking test condition according to IEC 60587 standard has been applied as proposed by the reference work in simulation using QuickField FEM software. The results show that the electric field and current density would become critical in higher applied voltage and contaminant flow rate. The highest average and highest maximum current density and electric field are found in both applied voltage of 6 kV and contaminant flow rate of 0.90 mlmin<sup>-1</sup>.</p>

Core Technology

Ion source provides sample ions for FAIMS. The key technology is ionization method. Efficient ionization of analytes is the core technology for data acquisition in high quality FAIMS systems. In order to long-distance detect and analyze harmful and toxic substances such as explosives, drugs, chemical reagents and environmental pollutants in an open environment, without pretreatment, real-time and on-line, the ion source control and its technical device using excessive electric field were designed and developed. The disadvantages of high flow rate of APCI and low flow rate of ESI are integrated, based on the chemical analysis principle of FAIMS, an experimental platform of ionization technology based on excessive electric field is proposed and designed, which mainly includes: ion focusing system, flat-panel migration zone with focusing structure, sample integration, etc. The experimental results show that the ion source based on excessive electric field can be widely used in biochemical weapon warning, drug tablet detection, environmental monitoring, food and drug detection and clinical medicine, and the detection limit can reach 0.1 ppm.
