Space-charge-flow computer program
C. D. Bogart, Edward A. Richley · NASA Technical Reports Server (NASA) · 1966
A description of a computer program for the solution of two-dimensional and axisym metric space-charge-flow problems is given.The program is written in FORTRAN IV for an IBM 7094 computer.Primary emphasis is placed on nomenclature, word defini tions, and programing procedures.The program overlay chart and subroutine flow dia grams a r e presented, and example sets of input and output data for a variety of boundary conditions a r e given and fully explained.The program has been applied extensively for the analysis of various electrostatic-thrustor-design concepts, wherein positive chargedparticle flow is conventional.It is equally applicable to various other problems, such as electron tube design in which the particles (electrons) have a negative charge.Output data listings include detailed information on potential distributions, particle trajectories, thrust, power and current densities, and other parameters of interest.I I ,
