HTML summary data

The following sections list the boundary conditions or other data and their corresponding values in the -_data.html file. For a transient solution, all data is stored for each time step. For steady-state solution, all data is stored at the final iteration.

Thermal Stream load data

The following table describes the data stored for each Thermal Stream load in the model.

Data Type Description
Tin Temperature Displays the stream inlet fluid temperature.
Tout Temperature Displays the stream outlet fluid temperature.
TrelOut-A Temperature Displays the outlet relative temperature on side A. The relative temperature allows for the rotational effects due to the swirl velocity.
TrelOut-B Temperature Displays the outlet relative temperature on side B. The relative temperature allows for the rotational effects due to the swirl velocity. For one-sided stream types, this value is zero.
Pout Pressure Displays the stream outlet fluid pressure.
Mout Mass flow Displays the stream outlet mass flow.
Dir Flow direction Displays the flow direction.
THR-A Heat rise Displays the total heat rise on side A.
THR-B Heat rise Displays the total heat rise on side B. For one-sided stream types, this value is zero.
CHR-A Heat rise Displays the convective heat rise on side A.
CHR-B Heat rise Displays the convective heat rise on side B. For one-sided stream types, this value is zero.
AREAC Area Displays the total corrected convective area.
AREAC-A Area Displays the corrected convective area on side A. For one-sided stream types, this value is the same as for AREAC.
AREAC-B Area Displays the corrected convective area on side B. For one-sided stream types, this value is zero.
SVout-A Swirl velocity Displays the outlet swirl velocity on side A.
SVout-B Swirl velocity Displays the outlet swirl velocity on side B. For one-sided stream types, this value is zero.

Thermal Convecting Zone load data

The following table describes the data stored for each Thermal Convecting Zone load in the model.

Data Type Description
Tmax Temperature Displays the maximum temperature on the wall.
Trel-max Temperature Displays the maximum relative temperature on the wall. The relative temperature allows for the rotational effects due to the swirl velocity.
Pmax Pressure Displays the maximum pressure.
THR Heat rise Displays the total heat rise.
AREAC Area Displays the corrected convective area.
SVmax Swirl velocity Displays the maximum swirl velocity.

Thermal Void load data

The following table describes the data stored for each Thermal Void load in the model.

Data Type Description
Tmax Temperature Displays the maximum temperature on the wall.
Trel-max Temperature Displays the maximum relative temperature on the wall. The relative temperature allows for the rotational effects due to the swirl velocity.
Pmax Pressure Displays the maximum pressure on the wall.
THR Heat rise Displays the total heat rise.
CHR Heat rise Displays the convective heat rise.
AREAC Area Displays the corrected convective area.
SVmax Swirl velocity Displays the maximum swirl velocity.

Immersed Duct simulation object data

The following table describes the data stored for each Immersed Duct simulation object in the model.

Data Type Description
CHR Heat rise Displays the convective heat rise.
AREAC Area Displays the convective area.
