Spectral computation of low probability tails for the homogeneous Boltzmann equation
John Zweck, Yanping Chen, Matthew J. Goeckner +1
We apply the spectral-Lagrangian method of Gamba and Tharkabhushanam for solving the homogeneous Boltzmann equation to compute the low probability tails of the velocity distributio…
