Dispatch Methods

Following are the dispatch methods.

Solve Temp

This dispatch method is available for the Propagate Temperature method.

Required Known Slots

• Inflow

• Outflow1

• Inflow Heat

• Outflow2

Required Unknown Slots

• Outflow1 Heat

• Outflow2 Heat

Method Details

This method simply distributes heat associated with Inflow to the two outflows. If Inflow is 0, the two outflow heats are zero. Otherwise:

(5.1)

(5.2)

Solve Salt

This dispatch method is available for the Propagate Salt method.

Required Known Slots

• Inflow

• Outflow1

• Inflow Salt Concentration

• Outflow2

Required Unknown Slots

• Outflow1 Salt Concentration

• Outflow2 Salt Concentration

Method Details

This method simply distributes salt associated with Inflow to the two outflows. If Inflow is 0, the two outflow salt masses are zero. Otherwise:

(5.3)

(5.4)

Outflow 1 and Outflow 2 Salt Concentrations are set to Inflow Salt Concentration (unless the flow is 0, then the concentration is 0 as well).

Solve Temp and Salt

This dispatch method is available for the Propagate Temp and Salt method.

Required Known Slots

• Inflow

• Outflow1

• Inflow Heat

• Outflow2

• Inflow Salt Concentration

Required Unknown Slots

• Outflow1 Heat

• Outflow2 Heat

• Outflow1 Salt Concentration

• Outflow2 Salt Concentration

Method Details

This method simply distributes heat and salt associated with Inflow to the two outflows. If Inflow is 0, the two outflow heats and salt masses are zero. Otherwise:

(5.5)

(5.6)

(5.7)

(5.8)

Outflow 1 and Outflow 2 Salt Concentrations are set to Inflow Salt Concentration (unless the flow is 0, then the concentration is 0 as well).

Solve Temp and DO

This dispatch method is available for the Propagate Temp and DO method

Required Known Slots

• Inflow

• Inflow Dissolved Oxygen Mass

• Inflow Ammonia Mass

• Inflow Heat

• Inflow Detritus Mass

• Outflow1

• Inflow Dissolved Organics Mass

• Outflow2

Required Unknown Slots

• Outflow1 Dissolved Organics Mass

• Outflow2 Dissolved Organics Mass

• Outflow1 Dissolved Oxygen Mass

• Outflow2 Dissolved Oxygen Mass

Method Details

This method simply distributes heat and DO masses associated with Inflow to the two outflows. If Inflow is 0, the two outflow heats and DO masses are zero. Otherwise:

(5.9)

(5.10)

(5.11)

(5.12)

(5.13)

(5.14)

(5.15)

(5.16)

(5.17)

(5.18)
