This tutorial is to show how the IAPWSThermo work in OpenFOAM
//***********************INFORMATION TO TEST CASE*******************************//
Important files in this case:
1. thermophysicalProperties
--> see thermotype
1. fvSolution
PISO subdict --> see the realFluid --> this must be true (see modification in the pEqn of realFluidPisoFoam)
2. controlDict:
the dynamic libraries used for the IAPWS 97 water properties are not directly link into OpenFOAM.
Therefore, the dynamic libraries need to be defined in controlDict
//************************NEW CODE NEEDED FOR THIS CASE*************************//
1. Code in OpenFOAM: $WM_PROJECT_DIR/src/thermophysicalModels/externalMedia/
just run wmake libso in the folder
2. FreeSteam: download the code @ http://freesteam.sourceforge.net/example.php
get the sourceCode --> I'm not sure of the packages work with this code
see README.txt file to see what libraries you need to compile freeSteam
//***********************Problems*******************************//
If problems occur using the IAPWS 97 water properties, please check the following points
1. have you suggesfully compiled freeSteam.
a: If no, have you installed gsl, scons and so on (see README.txt in the freeSteam)
b: If yes, is the libfreesteam.so in a folder where OpenFOAM finds it e.g. $WM_PROJECT_DIR/lib/linux64GccDPOpt
(last folder name depends on your machine, compiler ...)
2. have you compiled the thermophysical models that connect freeSteam to OpenFOAM. They can be found in this folder: $WM_PROJECT_DIR/src/
thermophysicalModels/externalMedia/
3. IS THE SOLVER STARTIGN TO RUN THE CASE? NO
check b23.c file at line 39 (or at least somewhere in the code:
if you find the following code:
return B23_N[4] + sqrt((pi - B23_N[5])/B23_N[3]) /* * 1{K} */;
change it to this:
return B23_N[4] + sqrt(fabs(pi - B23_N[5])/B23_N[3]) /* * 1{K} */;
