EHD RESEARCH

Abstract

The research in electrohydrodynamics is concerned with how charged particles can be generated in the laboratory with a potentially useful range of sizes, of charge, and of number density. It is suggested that refined measurement techniques are needed to check on just what is being injected into the flow. The effects of turbulence on the EHD process and, particularly, on breakdown are being studied. The report discusses in some detail the possible role of turbulence on the mean effective mobility of charged particles. On the experimental side, a laboratory facility was built and then improved by the addition of a larger test section and other equipment. Work is proceeding to further develop and refine the instrumentation. Two types of injectors were operated, namely, molecular and two phase, and the latter shows potential for efficient operation. It was concluded tentatively that turbulence in the carrier fluid increases its breakdown potential, and that turbulent air may be a suitable medium for the EHD energy conversion process.
