Approximate bimodal solutions for the integro-differential Boltzmann equation for the model of hard spheres are built in the case when the Maxwellian modes are screws with different degrees of infnite-simality of their angular velocities. Some suffcient c... see more

We find two fixed points differents of cero of the operator in an Sobolev Spaces in L¹ (?) with ? ? Rn and they are solutions of Boltzmann equation.

The new approximate solution for the nonlinear kinetic Boltzmann equation in the case of the model of hard spheres is found. It ensures the infinitesimality of the uniform-integral weighted discrepancy between the sides of the equation and very fast tends... see more

In the attempt of obtaining macroscopic models which describe the flow of electrons through a semiconductor crystal, many authors start from the Boltzmann transport equation, often using a generalized BGK type approximation for the collision operator. In ... see more

Research have been conducted about calculating the plasma temperature using Laser-Induced Breakdown Spectroscopy (LIBS), located in Udayana University’s Laboratorium Penelitian Terpadu FMIPA. The calculation of Plasma Temperature is done using the Boltzma... see more

The Boltzmann equation for an electron gas in a semiconductor is considered. The electron energy is assumed to have a very general form, so that, for instance, parabolic or non parabolic band approximations can be treated. A technique, which recalls the c... see more

This paper deals with an initial-boundary value problem for the discrete Boltzmann equation confined between two moving walls at different temperature. A model suitable for the quantitative analysis of the initial boundary value problem and the relative e... see more

At the conclusion of I. Bonzani's presentation on the existence of structured shock solutions to the six-velocity, planar, discrete Boltzmann equation (with binary and triple collisions), Greenberg asked whether such solutions were possible in directions ... see more

Least squares kinetic upwind meshfree (LSKUM) method has been the subject of research over twenty years in our research group. LSKUM method requires a cloud O of points or nodes and connectivity NP0 for every P0 € O. The connectivity of P0 is a set of nei... see more
