TP radforce-combustion

These practical works (PW) aim to familiarised the user at a concrete usage of a Monte Carlo Line Sampling approach in radiation field. The PW are based on a fork of RadForcE a Radiative Forcing Estimator in climate science used to compute radiative quantities integrated over the whole infrared range, the whole Earth and over a period of 10 years [1]. radforce-combustion is a declination of this code in combustion radiation for high temperature media.

Prerequisites

In order to compile the code:

In order to plot/show data:

Compilation

To compile radforce-combustion and the appropriate libraries run:

sh compile_library.sh

Do not forget to source the librairies with the following command :

source local/etc/profile

Practical exercise 1 (TP1)

See TP1/run.sh to run the code on defined cases.

Objective : run radforce-combustion to compute flux density at different position on the boundary on a cylindrical geometry.

Results : run line-by-line calculation on a few seconds in 3D on a computer. Attest gas, soot and wall contribution to the flux density.

Practical exercise 2 (TP2)

See TP2/run.sh to run the code on defined cases.

Objective : run radforce-combustion with complex boundaries (supershapes of thousands up to million of triangles)

Results : computation time is not dependent on the number of triangles of the boundary.
