Simple reactive sphere model

Np is the total number of beads in each PFPE molecule, (xg, yg, zg) are the coordinates of the PFPE molecular center of mass, and (x yir z() denote the bead coordinates. The perpendicular size of PFPE [Pg.108]

It was shown that the parameter a. is function of pressure p. /) is the reaction constant for surface-gas molecules interaction and is defined as [Pg.109]

In LBM, the slip velocity on the wall can be defined by applying streaming and bounce-back process. Typical bounce-back and slip condition on the wall in LBM can be expressed as [Pg.110]

Equation (50) physically has the same meaning as the Langmuir slip model when r is chosen as a. For the 3D case, the 5x5 matrix k can be easily built up by using r and s in the same manner as in 2D. [Pg.110]

A holistic strategy in hierarchical modeling, which enables the communication between physical phenomena in different length and time scales and provides understanding of the systematic properties using nanoscale parameters has been presented in this paper via two benchmark systems, that is, HDD and PEFC. By illustrating representative modeling methods on each level of scale, physical phenomena in each [Pg.112]
