We provide a linear analysis on normal modes of the spin Boltzmann equation proposed by Weickgenannt et al. [Phys. Rev. D 104, 016022 (2021)], where nondiagonal or polarized part transition rate is neglected to ensure Hermitian property linearized collision operator. As an instrumental element kinetic theory, conservation total angular momentum explicitly considered; thus, our relevant recent i...

In this paper, we examine how to build coarse-grain transport models consistently from the kinetic fluid regimes. The internal energy of gas particles is described through a state-to-state approach. A equation allows us study phenomena in phase space for non-homogeneous mixture. Internal excitation modeled using binary collision operator, whereas chemical processes rely on reactive operator. We...

Water quality control and the of contaminant spill in water particular are becoming a primary need today. Gradient descent sensitivity methods based on adjoint formulation have proved to be encouraging techniques this context for river channel flows. Taking into account that most channels rivers include junctions with other branches, objective study is explore technique network reconstruct upst...

This study presents numerical simulations of faecal coliforms dynamics in Luruaco lake, located Atl\'antico Department, Colombia. The velocity field is obtained through a two-dimensional horizontal (2DH) model Navier-Stokes equations system. transport equation concentration provided from convective-diffusive-reactive equation. lake's geometry built cubic spline and multi-block methods. discreti...
