rock¶
Assign rock density, specific heat and porosity.
| Input Variable | Format | Description |
|---|---|---|
| DENRD | real | Rock density (kg/m3). |
| CPRD | real | Rock specific heat \(\left( \frac{MJ}{kg \cdot K} \right)\). If CPRD > 1 the code will assume the units are \(\left( \frac{J}{kg \cdot K} \right)\) and multiply by \(10^{-6}\). |
| PSD | real | Porosity.
Special note on negative porosities. If the code encounters a negative porosity, the node at which the negative porosity occurs is effectively removed from the model. That is, the geometric connections from that node to other nodes in the model are removed. The volume associated with the node acts as a barrier to flow. For input purposes, the node may still be assigned properties, though they will have no effect on the simulation results. |
The following is an example of rock. In this example the nodes numbered
1 through 140 are assigned a rock density of 2563. kg/m^3,
a rock specific heat of 1010. J/(kg K) and a porosity of 0.35.
