A first order projection-based time-splitting scheme for computing chemically reacting flows, IMA-Preprint

open access: yes, 1998
. The simulation of chemically reacting ows in speci c situations is a basic instrument in natural sciences in order to understand complex phenomena e.g., salt concentrations in oceans as well as in engineering sciences e.g., the optimization of the

Long time decay of incompressible convective Brinkman-Forchheimer in L2(ℝ3)

open access: yesDemonstratio Mathematica
In this article, we study the global existence, uniqueness, and continuity for the solution of incompressible convective Brinkman-Forchheimer on the whole space R3{{\mathbb{R}}}^{3} when 4μβ≥14\mu \beta \ge 1.

AN ELLIPSOIDAL STATISTICAL MODEL FOR GAS MIXTURES

open access: yes, 2015
In this paper, we propose a construction of a new BGK model generalizing the Ellipsoidal Statistical Model ([2], [19]) to the context of gas mixtures. The derivation of the model is based on the introduction of relaxation coefficients associated to some ...

Time decay estimates of solutions to a two-phase flow model in the whole space

open access: yesAdvances in Nonlinear Analysis
In this article, we aim to establish the optimal time decay rates of strong solutions to a two-phase flow model derived from a type of coupled fluid-kinetic equation.

Optimal large time behavior of the 3D rate type viscoelastic fluids

open access: yesAdvances in Nonlinear Analysis
We investigate optimal decay estimates of solutions to the 3D Cauchy problem of the rate type viscoelastic fluids. The main novelty of this article involves three aspects: first, we show that the second-order and third-order spatial derivative of the ...
