Abstract : Rosen's restricted variational principle representation of the Boltzmann equation is used to analyze the mixing of two initially parallel low-density hypersonic streams. The mixing occurs as a result of convective, thermal, and collisional motions of the gas particles. Mixing zone, number density, and velocity profiles for a variety of initial temperature and velocity ratios are given for the Knudsen number range infinity < Kn < 0.2. (Author)
