 %SUMMARY Comb: Combustion chamber model
-%DESCRIPTION 
+
+%DESCRIPTION   This thermal tank model has been developed to represent an ideal
+%DESCRIPTION   (and non-dynamic) combustion chamber for a gas turbine. The major
+%DESCRIPTION   simplification is that the mass contained in the tank is assumed
+%DESCRIPTION   constant -- this is consistent with using an ideal compressor and an
+%DESCRIPTION   ideal turbine with identical mass flows. Energy conservation is
+%DESCRIPTION   ensured by using true bonds and components.
