 Description
     Eddy dissipation model based on the principle of mixed is burnt.
 
+    The time scale is determined by the minimum between the turbulent

 Description
+    Standard Eddy Dissipation Model based on the assumption that the
+    reaction rates are controlled by the turbulece time length scale.
+    The chemical reaction rate is governed by the large-eddy mixing scale,
+    (ie k/epsilon). Combustion takes place whenever the turbulence is present.
