NUMERICAL MODELLING OF A WIRE-NON-PARALLEL PLATE TYPE ELECTROHYDRODYNAMIC GAS PUMP
Numerical modeling was conducted for a wire-non-parallel plate type electrohydrodynamic(EHD)gas pump,where this type of pump already has demonstrated to generate significant gas flow rate to drive unidirectional flow for cooling of electronics systems.Analytical solution of the onedimensional ion transportation and Poissions equation in a cylindrical coordinate were used as numerical solution input for the two-dimensional mass and momentum equatmns based on k-epsilon model in a rectangular coordinate.The flow velocity field and pressure drop profiles were numerically calculated by the Phenics code.The effect of corona wire position with respected to the ground electrode edges and the flow channel conversion angle were numerically investigated.The results show that the pressure generation and gas flow rate increases with increasing EHD number,hence discharge current,applied voltage or discharge power.A significant ground wire positions and conversion angle effect were observed even angle as sinail as 0 to 5 degrees.
