The basic theory of space-charge flow is described, and three gen¬eral methods of solution are discussed. Specific space-charge-flow ge¬ometries are described in detail;these include flow between coaxial cylinders, concentric spheres, coaxial cones, hyperbolic flow, flow be¬tween inclined planes, and circular flow. Since all the solutions dis¬cussed are for space-charge-limited flow, a discussion of partial space-charge flow is presented. The Pierce method of electrode design is de¬scribed, and some practical limitations of this method are discussed. Electrode shapes for various space-charge flows are shown.
