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.

Usage

Property	Description	Required	Default value
`Df`	Fractal dimension	yes
`alphaC`	Scaling prefactor	yes
