Physical, mathematical, and computational models of neutral gas and rarefied plasma effusion into vacuum space have been considered in this chapter. Gas or plasma effusion is viewed as the process in which they escape from a container through a relatively small hole shaped like a narrow long slot. Results of computational experiments have been provided: the distribution functions of charged particles and neutral gas, their velocity field and concentration field. The impact of latitudinal magnetic field on the distribution functions and momentums of charged particles effusion has been studied. Parameters of evolutionary processes have been considered, from the moment, when the slot is formed through the transition of the effusion process into stationary mode. |
