WebbLet assume the closed Brayton cycle, one of the most common thermodynamic cycles found in modern gas turbine engines. In this case, assume a helium gas turbine with a single compressor and single turbine arrangement. One of the key parameters of such engines is the maximum turbine inlet temperature and the compressor pressure ratio … WebbThe second law of thermodynamics states that the total entropy of a system either increases or remains constant in any spontaneous process; it never decreases. An important implication of this law is that heat transfers energy spontaneously from higher- to lower-temperature objects, but never spontaneously in the reverse direction.
