udf for superheated steam?
 
i want make a transient thermal simulation with steam temperature (380 to 530C, pressure (5 to 18 MPa) and massflow (10 to 140kg/s ) should be varried. does anybody wrote a udf for material properties of superheated steam and time functions of mass flow or pressure and temperature.

thank you for your answers

I had written a UDF for steam according to IAPWS97,however it was had to vertify.Do you have experiment data for some benchmark?

i calculate components (thermal, stress) of great power plants. Experimental data of power plant has not a academic quality. i have two links http://ercoftac.mech.surrey.ac.uk/ and experimental data of air in a pipe for a lot of Re-numbers

http://www.princeton.edu/~gasdyn/ind...superpipe_data can you send me your udf an i check them only in numeric way for my steam data.

want udf file for the properties of superheated steam
 
I m doing simulation in pipe having cross over pipe....
I want that udf file for superheated steam.....
Can anyone send it to
Viralnagar5692@gmail.com
I hc found from some resources that IAWPS-IF97 code is used....also give me the model information


Thnks in advance

I will cross check t same with the numerical data from steam table
