“…In [31], it is noted that entropy generation due to dissipation caused by viscous layers, vortices and shocks is the reason for reduced system performance. Therefore, local contributions to the entropy generation can be determined using adequate turbulence modeling, leading to an overall performance evaluation based on entropy generation considerations.…”

“…Istotnym czynnikiem podnoszącym efektywność przemian energetycznych w układach z turbiną gazową jest temperatura spalin na wlocie turbiny. Podnoszenie tej temperatury wpływa na sprawność obiegu termodynamicznego oraz poziom mocy jednostkowej [1]. Wysoka temperatura spalin powoduje, że materiały, z których zrobione są łopatki muszą mieć określone własności termofizyczne, aby mogły pracować w takich temperaturach.…”

“…The leakage of flow through this tip clearance causes a number of adverse effects that result in a reduction in the overall efficiency of a turbine stage. It has been stated that the loss in turbine stage efficiency due solely to the tip clearance flow varies between 2% to 6% for a realistic clearance of 1% of blade span, and that this loss accounts for 20% to 40% of the overall loss within the turbine [1].The potential savings of reducing this unwanted loss is great. Lattime and Steinetz [2] reported that for only a 1% reduction in specific fuel consumption, the potential fuel savings for commercial U.S. airline carriers alone would be approximately 53 billion liters (14 billion gallons) annually.…”
