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.
TableBase, TableFile and Table now combined into a single simpler Table class
which handle both the reading of embedded and file data using the generalised
TableReader. The new EmbeddedTableReader handles the embedded data reading
providing the functionality of the original Table class within the same
structure that can read the data from separate files.
The input format defaults to 'embedded' unless the 'file' entry is present and
the Table class is added to the run-time selection table under the name 'table'
and 'tableFile' which provides complete backward comparability. However it is
advisable to migrate cases to use the new 'table' entry and all tutorial cases
have been updated.
using Function1 and supporting all the standard Function1s including tabulated
and coded.
tutorials/multiphase/interFoam/laminar/sloshingTank3D6DoF updated to use
sixDoFMotion.
The interpolationLookUpTable is highly specialised for absorptionEmissionModels
which did not need to be templated and is now located in the appropriate
directory and namespace.
The current rough wall functions cover most requirements and there is no clear
need to maintain nutUTabulatedWallFunctionFvPatchScalarField and associated
clutter.
This improves paraview's handling of VTK files which only contain
points. It means the points are visible without glyph-ing, and provides
the necessary input for some filters to operate correctly.
to improve robustness and maintainability. Now all switches and constants are
set correctly on constructions without the need for dynamic update after the
system/controlDict is read. This significantly simplifies the code and make it
much easier to add new switches, constants and settings without the need to
ensure they are registered to a database for update.
Description
Multi-component Fickian and eddy-diffusivity turbulent based temperature
gradient heat flux model for RAS or LES of turbulent flow with optional
Soret thermal diffusion of species.
Currently the diffusion coefficients are constant but temperature and
pressure dependency will be added.
The heat flux source is implemented as an implicit energy correction to the
temperature gradient based flux source. At convergence the energy
correction is 0.
Usage
\verbatim
RAS
{
model FickianEddyDiffusivity;
Prt 0.85;
Sct 0.7;
D (1e-5 2e-5 1e-5); // [m^2/s]
DT (1e-5 2e-5 1e-5); // [kg/m/s] Optional
}
\endverbatim
Moved the switch and constant reading functionality from TimeIO to more rational
locations.
Added registration of InfoSwitches which are not run-time controlled by other
means.
combustionModels now use the virtual functions provided by SpecieMixture to
avoid the complexity in code and compilation of templating on the ThermoType.
Additionally the models based on singleStepCombustion now use the concrete
reaction base class to avoid the templating on ThermoType introduced by the
Reaction type.
The streamLines function object now writes out "age" by default. This is
calculated as the total integration time from the starting point of the
streamline. This value can be negative if tracking is performed in the
reverse direction. Writing "age" can be deactivated by means of a
"writeAge no;" entry in the function object specification.
