Abstract:
An explicit approximate solution to the three-dimensional nonlinear Boltzmann equation for rigid spheres is constructed. It has the form of a spatially inhomogeneous linear combination of two Maxwellians corresponding to different densities, temperatures, and mass velocities. It is shown that the integral norm of the discrepancy between the left- and right-hand sides of the equation can be made arbitrarily small by choosing appropriate values of the parameters entering the distribution.
