On the boltzmann equation
Web4 de abr. de 2024 · A one-point second-order Dirichlet boundary condition for convection-diffusion equation based on the lattice Boltzmann method has been proposed. The unknown temperature distribution is interpolated from the distributions at the wall node and fluid node nearest to the wall in the direction of the lattice velocity. WebThe Boltzmann equation was given by Ludwig Boltzmann in 1872. In modern literature, the term Boltzmann equation is often in use in a more general sense, referring to any kinetic equation that shows the change of a macroscopic quantity in a thermodynamic system. These quantities can be energy, charge or particle number.
