Combustion multiphase flow simulation

[Athena Cai]

Hi all,

I am looking to simulate combustion in the process of dropping a lit matchstick into a jug with the inside surface coated in fuel (isopropyl alcohol). You can see the linked clip for reference.

Is combustion simulation possible in IBAMR? I believe my problem is probably of multiphase flow? I have looked through the multiphase flow examples, but have not found any details that might help my simulation building process. Do you have any suggestions for how I should build the simulation?

I have not been able to visualize the examples yet as the link to 'Visualizations of simulations that use IBAMR' (from the github.io 'About' page) leads me to Error 403:  Access forbidden.

Thank you for your time!

I think you will want to use something like a low Mach formulation to model combustion. Currently we have some work in progress to develop low Mach codes for phase change (solidification, evaporation, melting) but not combustion. If you were interested in developing a combustion modeling capability, we’d be happy to help.

Sorry that the visualizations link is broken — although even before it was broken, it was quite out of date. We should probably put together a new gallery.
