Combustion simulation

[sezerh24]

I am pretty new to trixi.jl. it seems to be a great code though.

is there a way to simulate hydrogen combustion by using compressible N-S equations in a pipe?

Compressible Navier-Stokes equations is definitely our business. Maybe also in a pipe if you could start with a 2D setup or have a 3D mesh in a format which Trixi would understand. Chemical reactions are less familiar to most of us. Could you give some details on your model? Is the reaction or the transformation of one species into another something that can be calculated point wise or written as a source term in the equations?

[sezerh24]

Eq 1 is the momentum equation
Eq 2 is the energy equation
Eq 3 is the species transport equation ( Scalar transport equation)
in Trixi.jl it seems that eqs. (1-2) are available. The equation 3 is just a scalar transport equation for one specie. If we have N species, we would have to put N scalar transport equations.
is it possible to solve the set of 3 equations given the above example? if so, Trixi.jl can be a very good option for the combustion community.

There are some examples with multi-component compressible Euler which I think are very close.

okay thank you, I will check them out and see if it can add them to the N-S equations.

I am currently verifying a set-up of Trixi with multi-species Euler with chemical reactions, hopefully I will have the repo up in a couple of weeks.

I look forward to see the repo for the multi-species Euler with chemical reactions.
