heating water in a bottle
Is it possible to use openfoam to model the heating of water in a closed bottle with a certain amount of headspace? I would like to measure the temperature of the water and the resulting pressure in the bottle as the water changes to water vapour in the headspace. Any ideas?
Thanks. |
Hi bigred.
I'm a little bit confused. What is a 'headspace'? Did you mistyped 'heatspace' and are meaning (specific) 'heat capacity'? |
The headspace is the volume of gas above the liquid surface in a sealed bottle. for example, a cola bottle is filled to a certain amount and the space that is left (between the liquid and the cap) is a headspace of CO2.
Hope this clarifies things and thanks for the interest. |
Hi bigred.
Sorry, I just wasn't sure but now everything is clear. So you will need a multiphase solver which is capable of handling phase change due to evaporation. I think there is an incompressible solver doing exactly this: interPhaseChangeFoam. Have a look into this thread: http://www.cfd-online.com/Forums/ope...aporation.html Hope this helps! |
