Detailed Description

This object reads thermodynamics values of fluids that are stored in files stored in MURE/thermal_data/.

example : case of heat capacity of light water In the h2o directory a file heatcapacity.dat is created with two columns In the first one are the temperatures In the second one are the heat capacities values for each temperature All this values do not depend of pressure : only liquid phase is computed Data tables stored do not need to be fine discretized : a cubic spline interpolation is implemented to check out values.
