Following functionality added:
- support of dimensional inputs
- run time selection mechanism of HTC model (kappaEff, ReynoldsAnalogy)
- kappaEff has now two options for calculating HTC (with/without characteristic length)
- Reynolds Analogy estimation for HTC
- integrated HTC replaced with an average log output
Description
Calculates and writes the estimated heat transfer coefficient at wall
patches as the volScalarField field.
All wall patches are included by default; to restrict the calculation to
certain patches, use the optional 'patches' entry.
The models are selected run time by model entry. For detailed description
look at the header file for specific model under
wallHeatTransferCoeffModels.
Example of function object specification:
\verbatim
kappaEff1
{
type wallHeatTransferCoeff;
libs ("libfieldFunctionObjects.so");
model kappaEff;
...
region fluid;
patches (".*Wall");
rho 1.225;
Cp 1005;
Prl 0.707;
Prt 0.9;
}
\endverbatim
\verbatim
kappaEff2
{
type wallHeatTransferCoeff;
libs ("libfieldFunctionObjects.so");
model kappaEff;
...
region fluid;
patches (".*Wall");
rho 1.225;
Cp 1005;
Prl 0.707;
Prt 0.9;
Lchar 0.001;
}
\endverbatim
\verbatim
ReynoldsAnalogy1
{
type wallHeatTransferCoeff;
libs ("libfieldFunctionObjects.so");
model ReynoldsAnalogy;
...
region fluid;
patches (".*Wall");
rho 1.225;
Cp 1005;
Uref 1.0;
}
\endverbatim
Note
Writing field 'wallHeatTransferCoeff' is done by default, but it can be
overridden by defining an empty \c objects list. For details see
writeLocalObjects.
