In Gl. 2.57 bedeutet h_t5^*die Enthalpie am Turbinenaustritt. Die Kühlluft, die in der Turbine dem Gasstrom wieder zugeführt wird, soll hier rechnerisch hinter der Turbine isobar zugemischt werden. Damit wird dann:
In GL. 2.57 means h_t5 ^ * the enthalpy at the turbine outlet. The cooling air is fed back to the gas flow into the turbine, to be mixed in here computationally isobar behind the turbine. It is then:
In Eq. 2:57 means h_t5 ^ * the enthalpy at the turbine outlet. The cooling air, which is supplied to the turbine in the gas stream again, is to be arithmetically added isobar behind the turbine here. Thus becomes:
In EQ. 2.57 Means h_t5 * the enthalpy at the turbine exit. The cooling air which is fed back the gas flow in the turbine, this is designed to be mixed isobaric basis constructed downstream of the turbine. It will then be:
