First-order kinetic approximation for a reactive gas mixture

A Gas-kinetic Scheme for Reactive Flows

In this paper, the gas-kinetic BGK scheme for the compressible flow equations is extended to chemical reactive flow. The mass fraction of the unburnt gas is implemented into the gas kinetic equation by assigning a new internal degree of freedom to the particle distribution function. The new variable can be also used to describe fluid trajectory for the nonreactive flows. Due to the kinetic gove...

Approximation of flammability region for natural gas-air-diluent mixture.

The growing implementation of exhaust gas recirculation (EGR) in reducing NO(x) emissions of engine is of paramount motivation to perform a fundamental research on the flammability characteristics of fuel-air-diluent mixtures. In this work, the influences of EGR on the flammability region of natural gas-air-diluent flames were experimentally studied in a constant volume bomb. An assumption of c...

First Order Approximation for Texture Filtering

Texture mapping is a core technique in 3D graphics and is important for computer vision applications as well. The major challenge of texture mapping is high quality antialiasing at a reasonably high speed. Previous approaches do not address this problem adequately, since they do not precisely model the anisotropic and spatially variant nature in texture mapping. In this paper, we handle this pr...

A method for solving first order fuzzy differential equation

First-order cancellation of the Cs clock frequency temperature-dependence in Ne-Ar buffer gas mixture.

Through the detection of Coherent Population Trapping (CPT) resonances, we demonstrate the temperature-dependence cancellation of the Cs clock frequency in microfabricated vapor cells filled with a mixture of Ne and Ar. The inversion temperature at which the Cs clock frequency temperature sensitivity is greatly reduced only depends on the partial pressure of buffer gases and is measured to be l...
