Documentation du code de simulation numérique SUNFLUIDH

This data setup is only used in the full version of sunfluidh for the simulation of reactive gas flows under low-Mach number hypothesis.
It provides some information on the nature of the chemical reactions. The kinetic mechanisms must be described in specific files planned to be directly compiled with the code (see …).
This data setup is recommanded for expert users only.

• Type : boolean value
• This data allows the code to access (or not) to any specific procedures used for calculating the the chemical part of the reactive flow simulations.

• Type : integer value
• Number of chemical reactions

• Type : real value
• Time from which chemical reaction are activated

• type : real value
• Time range for which the reaction rates are damped (in order to reduce the stiffness of equations)

• Type : real value
• Specify whether the reaction rates depend on the density

• Type : boolean value
• Specify whether the reaction rates depend on the temperature

• Type : boolean value
• Specify whether the time-variation rate of the energy depends on the heat capacity of the species.

• type : boolean value
• This option allows the user to test the kinetic mechanism in the case of a homegeneous reactor (without flow consideration)
• In this case, the Navier-stokes equations are not considered.
