Abstract:

Rosens restricted variational principle representation of the Boltzmann equation is used to determine the free molecular mixing of two initially parallel gas streams of differing temperature and speed ratio. Mixing is accomplished by means of thermal and convective motions of the gas particles. It is shown that the variational method leads to a rapid calculation scheme for number density and velocity results of the method compare closely to exact special function solutions of the collisionless Boltzmann equation.
