flux equation
2.The simplified spherical harmonics(SPN) method is utilized to discrete the angular variables of Self-Adjoint Angular Flux(SAAF) neutron transport equation as spherical harmonics method has the dis-advantage of large amount of calculation. To solve the unstructured geometry problem,the spatial variables of ics(PN) method,and can save more time when dealing with problems with higher dimension,larger amount of meshes,and larger expanding order N.
5.The two-dimensional body-fitted grid was created by method of partial differential equation and zonal method. The k-equation subgrid-scale model was used to simulate the turbulent viscosity, the chemical reaction rate was determined by the subgrid EBU combustion model and the heat flux model was employed for the heat flux.
6.The simultaneous solution of the generalized Reynolds equation,three-dimensional energy equation,three-dimensional heat transfer equation and force equilibrium equation were presented and the changes of the lubricant viscosity and density with the temperature and pressure were taken into account. Consequently,the three-dimensional temperature field was obtained with the heat flux continuity condition imposed at the interface between the oil film and the bush.
9.Based on the consideration of the contribution of pH value, initial concentration of fluorobenzene, ozone flux and reaction temperature to the ozonation process, a simplified mechanistic model for fluorobenzene degradation by ozone was derived, and the kinetic reaction equation was fitted as an exponential function: C = C0exp(-0.324 exp(-7437/RT) QO30.41C0-0.372[OH-]0.0942t).
