Thermo properties
 
Hi Foamers,

Im doing some simulation about a case (version 1.5) where the fluid properties depend on the temperature... I would like to know if we can define non constant properties in OF and how to do it
Thanks in advance

Hi Foamers,

I have no answer so maybe i will try to give more explanation.
In my case i have 2 solids where Cp and k (thermal conductivity) are both a function depending on temperature.
I would like to define this function in the thermal properties dictionnary. but i dont know how to do it, or if it's possible.

I search in the forum any threats but i didnt find one. I started OpenFOAM a few weeks ago so maybe my research was wrong.

Thanks in advance
Kyian

Hi sivakumar

I will try to explain u again. sorry for my english...

In my case, the solid and fluid properties (Cp and the thermal coefficient K) are not constant but depend on the temperature. In fact, cp and K are both a linear function depends on temperature.
I would like to know if it's possible to enter this equation and how to do it.
I hope it's clearer this time

Where can I find the last version of OF to download? Is it easy to install? What´s the distribution of linux (32 bits) i must use?

hi,
you can download openFOAM latest veriosn, go to the website http://www.opencfd.co.uk/openfoam/linux.html and select linux 32 bit, download all (openFOAM software and third-party software)
to install the openFOAM just go through the README file.
