Numerical lnvestigation of Disturbance Environments in Low Pressure Turbines
… various disturbance environments existing in a low pressure turbine (LPT) are investigated. In particular, the effects of free-stream turbulence (FST), unsteady wakes, roughness and blade oscillations on the separation-induced transition on the suction surface of a low pressure turbine blade are …

Heat Transfer, Transition, And Aerodynamic Loss In A Linear Vane Cascade At Low Reynolds Numbers In High Speed Flows
<p>Low pressure turbine research is essential for improving the efficiency of the modern gas turbine engine. At high altitude cruise conditions, the low pressure turbine experiences low Reynolds number flow, which produces a laminar boundary layer on airfoil surfaces. The integrity of the laminar …

Investigation and design of a secure, transportable fluoride-salt-cooled high-temperature reactor (TFHR) for isolated locations
… fuel injection port between the high and low pressure turbines which can be used to raise the temperature of the working fluid and boost the power extracted from the system by up to 50%. This increase of electric output occurs without changing the power drawn drawn from the reactor, …

Influence of the heat treatment procedure on the stress corrosion cracking behaviour of low pressure turbine blade material FV566
… is one of the leading damage mechanisms in low-pressure turbines in the power generation industry; in LP turbine blades it primarily occurs in the last stage blades. The research investigated the influence of tempering temperature on the microstructure, mechanical properties, and stress …

CFD Modeling of Separation and Transitional Flow in Low Pressure Turbine Blades at Low Reynolds Numbers
… prediction for turbine engines operating at low Reynolds numbers. In this regime, boundary layer separation may be more likely to occur in the turbine flow passages. For accurate CFD predictions of the flow, correct modeling of laminar-turbulent boundary layer transition is essential to …
