Numerical Analysis of Electrical Characteristics in a Squared Channel EHD Gas Pump
Corona discharge characteristic is highly dependable on working medium, the system setup, and the ambient condition. With a numerical analysis, the impact of high voltages on the electrical characteristics during EHD (electrohydrodynamic) pumping in a square channel is investigated with a wide range of high applied voltages. The conductor setup is settled with three types of pin configuration. Also, each conductor is tested for three different width ground plates. Simulation model consists of a conductor, ground plate, and square flow channel (6.0-inch). The material for the square channel is glass; copper is selected for both conductor and ground plate. The results of the numerical study showed that the use of different numbers of conductor pin and change in ground plate width have a great impact on the EHD electrical characteristics with a significant deviation of forces on ground plate, conductor, test region and square channel are found.
