Description🔗
The heatTransferCoeff
function object computes
the heat transfer coefficient as a volScalarField
for a set of patches.
Operands🔗
Operand | Type | Location |
---|---|---|
input | - | - |
output file | - | - |
output field | volScalarField |
$FOAM_CASE/<time>/<outField> |
Usage🔗
Example of the heatTransferCoeff
function object
by using functions
sub-dictionary in system/controlDict
file:
heatTransferCoeff1
{
// Mandatory entries (unmodifiable)
type heatTransferCoeff;
libs (fieldFunctionObjects);
field <field>;
patches (<patch1> <patch2> ... <patchN>);
htcModel <htcModel>;
UInf (20 0 0);
Cp CpInf;
CpInf 1000;
rho rhoInf;
rhoInf 1.2;
// Optional (inherited) entries
result <fieldResult>;
region region0;
enabled true;
log true;
timeStart 0;
timeEnd 1000;
executeControl timeStep;
executeInterval 1;
writeControl timeStep;
writeInterval 1;
}
where the entries mean:
Property | Description | Type | Required | Default |
---|---|---|---|---|
type | Type name: heatTransferCoeff | word | yes | - |
libs | Library name: fieldFunctionObjects | word | yes | - |
field | Name of the operand field | word | yes | - |
patches | Names of the operand patches | wordList | yes | - |
htcModel | Model for coefficient computation | word | yes | - |
UInf | Reference flow speed | scalar | yes | - |
rho | Fluid density | scalar | yes | - |
The inherited entries are elaborated in:
Example by using the postProcess
utility:
postProcess -func "heatTransferCoeff(<field>)"
The following options are available for the htcModel
entry:
-
ReynoldsAnalogy
: Reynolds analogy
-
localReferenceTemperature
: local reference temperature
-
fixedReferenceTemperature
: fixed reference temperature
