Simulating H2 diffusion into Air

[Akshay U N]

I just installed FDS today, I was planning to validate one of the of my Open Foam simulation regarding the H2 diffusion into ambient air which I did using rhoReactingBuoyantFoam solver in Open Foam.

Since I am new to FDS I have few questions,

1) So does the simulation performed in FDS also consider buoyance of the gas?

2) Since I am beginner when it comes to this solver any help regarding the already available case scenarios or relevnt cases will be very helpful and appriciated

3) Which examples should I go through to perform the gas diffusion simulation?

Thank You

"gas diffusion" is not very descriptive. Can you describe the scenario in more detail.

I want to model dispersion of hydrogen into air at ambient conditions, I am looking for models which consider H2, O2, and N2 as scalars (also assigns air initially in my domain later when I let H2 into this domain through an angles inlet, I need to simulated the Lower ignition level region for h2 in this domain.

Thank you

You can specify individual gas species with FDS, and H2,O2, and N2 are all predefined species.

Since I am a beginner it would help a lot if I get similar case examples or tutorials to go through.

could you please refer to any present examples if they are already available.

Thank you

As a new user you should read the FDS Tech Guide, User's Guide, Verification Guide, and Validation Guide. All cases in the User and Verification Guides are installed in the directory where you installed FDS. All Validation inputs are available on the FDS github site: https://github.com/firemodels/fds/

Thanks for the information.
