A nonlinear gyrokinetic simulation model incorporating equilibrium current has been formulated for studying kinetic magnetohydrodynamic processes in magnetized plasmas. This complete formulation enables gyrokinetic simulation of both pressure-gradient-driven and current-driven instabilities as well as their nonlinear interactions in multiscale simulations. The gyrokinetic simulation model recov...

The bubble effectiveness in liquid phase cylohexane non-catalytic oxidation process is discussed in this paper. Then the bubble effectiveness and a new proposed kinetic model are used in the mathematical model of the industrial reactor for the cyclohexane non-catalytic oxidation process. Furthermore, simulation and optimization based on this reactor model are carried out. The results of sim...

A new hybrid kinetic electron model is developed for electrostatic full-f gyrokinetic simulations. The model is verified by computing the neoclassical transport and the linear ion temperature gradient driven trapped electron mode (ITG-TEM) stability. Impacts of kinetic electrons on the ITG turbulence are investigated, and a new saturation mechanism due to corrugated density profiles, which are ...

For increasingly rarefied flowfields, the predictions from continuum formulation, such as the Navier–Stokes equations lose accuracy. These inaccuracies are attributed primarily to the linear approximations of the stress and heat flux terms in the Navier– Stokes equations. The inclusion of higher order terms, such as Burnett, or high-order moment equations, could improve the predictive capabilit...

Thermal decomposition of organic matter under inert atmospheric conditions, leading to the release of volatiles and formation of cha is called as pyrolysis. It is also a first step in the biomass gasification. To design of a suitable pyrolysis reactor, understanding of kinetic parameters is essential. In the proposed kinetic model of this study, biomass decomposition is represented as a decompo...
