Rate of volume change (m^3/s) for the adjacent reactors.
The volume rate of change is given by
\[ \dot V = K A (P_{left} - P_{right}) + F(t)
\]
where K is the specified expansion rate coefficient, A is the wall area, and and F(t) is a specified function evaluated at the current network time. Positive values for expansionRate correspond to increases in the volume of reactor on left, and decreases in the volume of the reactor on the right.

Heat flow rate through the wall (W).
The heat flux is given by
\[ Q = h A (T_{left} - T_{right}) + A G(t)
\]
where h is the heat transfer coefficient, A is the wall area, and G(t) is a specified function of time evaluated at the current network time. Positive values denote a flux from left to right.

Add Jacobian terms proportional to derivatives of the wall expansion rate.
Adds entries for coeff * d(expansionRate)/dy_j to the specified global row of the reactor network Jacobian. The wall supplies scalar derivatives with respect to left and right pressures, while adjacent reactors supply pressure derivatives with respect to their state variables.
- Parameters
-
| [in,out] | trips | Sparse Jacobian entries. Implementations append entries using global row and column indices in the reactor network. |
| row | Global row index receiving these chain-rule terms. |
| coeff | Multiplicative factor applied to d(expansionRate)/dy_j. |
| includePressureSpecies | Include pressure derivatives with respect to species state variables when pressure is a derived quantity. These terms may be dense and are controlled by preconditioner sparsity settings. |
