hflx¶
Heat flow input.
A negative heat flow indicates heat flow into the reservoir.
| Input Variable | Format | Default | Description |
|---|---|---|---|
| QFLUX | real | If QFLXM = 0, then QFLUX is the heat flow (MW). If QFLXM ≠ 0,
then QFLUX is a temperature (oC) and the heat flow is
calculated according to the formula:
\(Q_H = QFLXM \cdot (T-QFLUX)\) (MW).
|
|
| QFLXM | real | If QFLXM > 0, multiplier for heat flow equation given in QFLUX
description (MW/oC). This must be large for large temperature gradients,
or when a constant temperature must be maintained.
If QFLXM < 0, then QFLUX is interpreted as a fixed saturation and
\(Q_H = ABS(QFLXM) \cdot (S_l - QFLUX)\) (MW).
|
Note
If the parameter QFLUX is set to -999, there will be fixed temperature from restart.
The following is an example of hflx. In this example, at each node from 401 to 410,
a heat flow of 0.001 MW is being injected into the model.
| hflx | ||||
| 401 | 410 | 1 | -0.001 | 0.0 |
In this example, QFLUX is set to -999 (see note above).
