Studies of the Effects of Electrostatic Fields on Fluid Flows

摘要

An overall review of studies of electrostatic interactions with fluid flows is presented. Review of prior studies involving ions with free convection, and channel flows is presented along with prior studies of field effects on condensation. The cause of large changes in laminar channel flow with ionization was studied both analytically and experimentally. The changes were determined to result from an electrically induced destabilization of the flow. External ion-flow boundary layer actions were studied and some influence on transition was found. Significant changes to frost formation and flame heat transfer under the action of an impressed E field were found. The possible use of ions injected into a gas stream as a flow diagnostic technique was explored and is considered a very logical area for future exploration. (Author)
