HIC Constant Water Activity

This model implemments the HIC isotherm assuming a constant water activity as described by Jäpel and Buyel [15].

\[\begin{split}\begin{align} \beta &= \beta_0 e^{c_{p,0}\beta_1} \\ \frac{\mathrm{d}q_i}{\mathrm{d}t} &= k_{a,i} c_{p,i} \left( 1 - \sum_j \frac{q_j}{q_{max,j}} \right)^{\nu_i} - k_{d,i} q_i 0.1^{\nu_i \beta} \end{align}\end{split}\]

• Component \(c_0\) is assumed to be salt without a bound state.

• Multiple bound states are not supported.

• Components without bound state (i.e., salt and non-binding components) are supported.
