WebThe diagram of a Brayton Cycle with reheat is shown below. The net power, Wat is the sum of the power produced by the two turbines minus the power required at the compressor W = W + Win-Wup. The total heat input, Quis made up of both the heat and the reheat processes: Q = Q wat+Qnet Then the thermal efficiency of the cycle is still - 3 ... WebIn general, the Brayton cycle describes the workings of a constant-pressure heat engine. It is one of the most common thermodynamic cycles found in gas turbine power plants or airplanes. In contrast to the Carnot cycle, the Brayton cycle does not execute isothermal processes because these must be performed very slowly.
