A Possible Solution for the Boltzmann Equation

Abstract

Recently there has been an interest in utilizing recent advances in nonlinear partial differential equations solution methods, the equivalent description by stochastic calculus methods, and the state function level of information entropy to the solution of several nonlinear PDEs that are well known in application to problems of gases and fluids and regular to turbulent flow in physics. A recent reported solution has been to the Boltzmann equation. Previously advances were made in solutions to the Navier-Stokes equations of gaseous flow. In this article we derive a possible solution to the 3D Boltzmann equation utilizing transformation methods at the macroscopic functional level, the PDF distribution and stochastic differential equation level. The collision integrals are evaluated utilizing the hypothesis of semiclassical collisions and are obtained from a maximum entropy approach. The collision integral evaluated beyond the molecular chaos approximation, it is 'added' to the phase space variational principle and the Boltzmann equation is transformed to a Fokker-Planck equation which is solved by several known methods both for computational and mathematical analytical applications.
