+It 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 :
+   * //**polyn_coef_for_rev_reactions.inc**// : Polynomials coefficients for calculating the reversed kinetic rate constant.
+   * //** kinetics.inc**// : Calculation of the kinetic rate constants.
+   * //** reaction_rates.inc **// : Calculation of the reaction rates.
+An explanation note is included in each file.\\
+Examples of chemical mechanisms are given in the sunfluidh directory : /TRUNK/DATA/REACTIVE_FLOW_DATA \\
+All new data set on chemical mechanisms must be defined in a specific directory which must be stated in the make file in order to download the files *.inc in the SOURCES directory during the compilation procedure.\\

+===== Definition of the data set =====
 -----
 ==== Chemical_Reactions_Enabled ====
    * 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.
+   * Default value= .false.
 ==== Number_of_Reactions ====
    * Type : integer value
    * Number of chemical reactions
+   * Default value = 1
 ==== Start_Time ====
-   * type : real value
+   * Type : real value
    * Time from which chemical reaction are activated
+   * Default value = 0.0
 ==== Reaction_Rate_Damping_Time ====
    * type : real value
    * Time range for which the reaction rates are damped (in order to reduce the stiffness of equations)
+   * Default value= 0.0
 ==== Density_Dependency_Enabled ====
-   * type : real value
+   * Type : Boolean value
    * Specify whether the reaction rates depend on the density
+   * Default value= .true.
 ==== Temperature_Dependency_Enabled ====
-   * type : boolean value
+   * Type : Boolean value
    * Specify whether the reaction rates depend on the temperature
+   * Default value= .true.
 ==== Heat_Capacity_Dependency_Enabled ====
-   * type : boolean value
+   * Type : Boolean value
    * Specify whether the time-variation rate of the energy depends on the heat capacity of the species.
+   * Default value= .true.
 ==== Homogeneous_Reactor_Enabled ====
-   * type : boolean value
+   * 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.
+   * Default value= .true.
