High voltage electrostatics and corona discharge are utilized for various applications in pollution and environmental control. The traditional applications have many flaws due to improper construction of electrode design and assembly that cause system failure, in particular when electrically stimulated devices are exposed to high humidity. A new innovative-patented design by Hamade, electrically stimulated catalytic converter (ESCC), eliminates such flaws and shows the wide practical applications of the new design. The new design utilized previous patented designs and work of the same inventor but retrofitted for catalytic auto exhaust emission control. The current and previous patents include: employing electrically stimulated filtration (ESF) to replace high efficiency particulate air (HEPA) filters, treatment of biological and infectious diseases, electret fabrication, and, most notably, the invention of a new electrically stimulated catalytic converter (ESCC). The electrically stimulated catalytic converter invention includes an exhaust conduit fed from the engine exhaust port with a housed corona charger apparatus. The opposite end is opened to the atmosphere outside of the vehicle or connected to a reduced-size catalytic converter. The corona charger is intrusively or non-intrusively associated with a main flow path defined by the exhaust conduit. The corona charger includes at least one electrode, which may be recessed away from, the main flow path. A plurality of corona chargers may be used in various combinations, optimally a two dimensional grid. The electrically stimulated catalytic converter is adapted to treat and eliminate auto exhaust pollution emission to air. 相似文献

The research on microfluidic droplet size prediction has been extensive and fruitful, while the droplet deforming process has been seldom studied. In this paper, a frying-oil-assessing microfluidic device was designed to study the droplet deforming and recovering processes, which were dominated by channel geometry, flow rates, sheath flow viscosity and interfacial tension of the two phases. Theoretical expressions of the deforming process and its extreme value were obtained for the first time, supported by simulation and experiments. Theoretical, simulation and experimental results indicated that the steady-state droplet length could be a useful parameter for frying oil assessment. 相似文献

为了研究反向扩孔气动冲击器内部气体流动阻力损失对其性能的影响,在简化复杂的气路基础上,从其结构和工作原理出发,分析了冲击器工作过程中气体流动所产生的压力损失;在有压力损失的条件下,研究冲击器气腔内气体变化特性,建立了冲击器的工作过程数学模型;根据数学模型,应用MATLAB程序进行计算机仿真运算,得到了冲击器工作过程中压力损失曲线,以及压力损失条件下活塞运动特性和各腔压力变化规律.研究结果表明:气体流动阻力损失影响冲击器破岩效率,使得冲击器活塞运动末速度从5.05 m/s下降到4.22 m/s,冲击频率从5.00 Hz下降到4.28 Hz;冲击器尾气压力仅为0.140 MPa,低于设计值0.185 MPa,影响冲击器尾气排屑. 相似文献
