Abstract
An investigation of the effects of ion motion on the pressure drop and heat transfer of a gas flowing in a channel was undertaken. Air and other gases were ionized within the channel and an electrostatic field was applied normal to the flow direction. Increases in pressure drop and heat transfer of the order of two to one were found with the application of the field. It was also observed that the velocity profiles in the channel were greatly distorted due to the action of the field. Extensive data are presented on the variation of friction factor, velocity profile, and heat transfer with ion current. The significance of these results lies in the fact that large changes were observed when the ionization level is very low, of the order of 1 ion to 10 to the ninth power neutrals in gas at standard conditions.
