Abstract
An analysis was performed on the actions of ions in a laminar flow stream. The analysis seeks to provide an explanation for the unusually high pressure drops found during a preceding experimental program involving laminar flow of ionized gas with an applied electrostatic field. The analysis revealed that very high pressure drops could be expected and that velocity profile distortions would occur. Good correlation with test data was achieved. A new nondimensional parameter, called the charge number, was introduced. Charge number is related to the Knudsen number and is the controlling parameter for ion action in the gas stream. The conclusion is that ions bound electrically to a flow stream set up an internal field on the stream, and then tend to resist the motion of the stream. This action causes profile distortions and increases effective fluid friction.
