Example results for an inhomogeneous PBE

The realizable schemes developed in the preceding section are applied to the moment distributions shown in Eigure 8.2. The normalized moments are defined by dividing their values by the initial values at x = 0 (1, 10, 200, 6000, 240 000). Eor the cases with constant diffusivity, we set M = 20, while for those with Stokes-Einstein diffusivity we use 0 = 1, and set M = 100 to improve the representation of the volume-dependent diffusive fluxes. 

As in the previous case, all of the abscissas used to represent the NDF are independent of x and t. The high-order advection and diffusion schemes are used almost everywhere in the domain for f 0.
