Friction factors, velocity distributions, pressure gradients, and density measurements were made on a 58-inch x 5-inch rectangular flow channel with air flow. A plane of corona wires along the midplane of the channel was the source of ions which drifted across the air flow to the electrically grounded walls of the channel. Experimental data were collected to determine the influence of the ion flow on the air flow and the extent of the ion-fluid coupling. The electrodynamic and hydrodynamic equations were set up and several approximate solutions were obtained based on the postulation of a flow induced body force and the assumption of fully established, one-dimensional flow. The magnitude of the ion effects was found to be significantly dependent on the ion density distribution within the flow channel.
