Detailed Description

Class for modelling the shape of particle aggregates using the concept of fractal geometry. Returns a collisional diameter.

$d_{c_i} = \frac{6}{\kappa_i} \left( \frac{v_i \kappa_i^3}{36 \pi \alpha_c} \right)^{1/D_{f_i}}\,,$

computed from a constant fractal dimension $D_{f_i}$ and a field-dependent surface area to volume ratio $\kappa_i$ , assuming that the primary particles in an aggregate have the same size.

The effect of sintering, i.e. the coalescence of primary particles resulting in a loss of surface area, is taken into account by a separate source term in the transport equation for $\kappa_i$ .

Usage

Property	Description	Required
`kappa`	Initial and boundary condition value	yes
`Df`	Fractal dimension	yes
`alphaC`	Scaling prefactor	yes
