In this paper we derive a new energy identity for the general threedimensional incompressible Navier-Stokes equations by the virtue of a special structure of helicity.
In this paper,an example was given to show the result of applying molten iron railway scheduling system by the logistics simulation technology,some parameters were computed from the simulation system
Designing optimal hyperbolic regularized method for moment system of kinetic equations is a challenging problem,which has been studied in different reduction models for many years.Developing from NRxx
The maximum entropy closure is widely regarded as the most reasonable candidate for modelling radiative transfer,but its implementation suffers huge numerical difficulties.We discovered an approximati
Using addition of hydrogen in gasoline fuels,this study aims at reducing heavy air pollution and carbon emissions produced by international combustion engines.Good agreement between experiments and 3-
An efficient numerical method is developed for computing the band structures of two-dimensional photonic crystals which are honeycomb lattices of circular cylinders.Using the Dirichlet-to-Neumann(DtN)
Many porous media applications exhibit complex microstructure and are multiscale in nature.The possible applications include heat conduction in metallic foams and lithium ion batteries,We develop a mu
