A test particle Monte Carlo method

Abstract

A Monte Carlo technique was developed suitable for investigating rarefield gas dynamics problems. The procedure is based on the `test particle' method. The discontinuous function frequently employed for describing the target molecules' velocity distribution is replaced here by a continuous analytic function, the form of calculations. This modification simplifies the calculations, reduces the computer storage requirements, and facilities the application of the method to multi-dimensional problems. The accuracy and versatility of the technique was evaluated by obtaining solutions to several one dimensional problems for which other results exist.
