On the boltzmann equation

Web22 de jun. de 2024 · Under equilibrium, the Boltzmann equation predicts that the velocity of the molecules is uncorrelated in space and time, and they follow the Maxwell–Boltzmann distribution [6–8]. Its equivalent description in hydrodynamics is force-free Euler equation that exhibits a random flow whose energy spectrum is proportional to k 2 [ 19 , 20 ]. Webclass of terms from this expansion and argued that it gives the Boltzmann equation. To the second order in the coupling constant, Hugenholtz’s claim was proved by Ho and Landau [6]. Beyond that it is not even clear that these terms satisfy the Boltzmann equation order by order, partly due to the complicated selection rules.
