The reason for this result can be considered as the combustion rate among the physical properties of each gas. WebJun 30, 2016 · This is due to the fact that the amount of fuel mass flow increases for a given amount of fuel energy when the Wobbe index is reduced. This increases the mass flow though the turbine section, which increases the output of the turbine. This effect is to some degree counteracted by the fact that the compressor pressure ratio increases to push the ...
