RISNumerical Study of Purge and Secondary Flows in a Low-Pressure Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The secondary flow increases the loss and changes the flow incidence in the downstream blade row. To prevent hot gases from entering disk cavities, purge flows are injected into the mainstream in a real aero-engine. The ...
Numerical Investigation of Contrasting Flow Physics in Different Zones of a High Lift Low Pressure Turbine Blade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Using a range of highfidelity large eddy simulations (LES), the contrasting flow physics on the suction surface, pressure surface, and endwalls of a lowpressure turbine (LPT) blade (T106A) was studied. The current paper ...
Numerical Investigation on the Cooling Effectiveness and Pressure Loss of a Novel Laminated Cooling Configuration With Cellular Partition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The laminated cooling is believed to be a promising cooling scheme for the next generation of advanced gas turbines. In order to build a cooling system with high performance, it is necessary to develop a more revolutionary ...
A Mixed-Fidelity Numerical Study for Fan–Distortion Interaction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Inlet distortion often occurs under off-design conditions when a flow separates within an intake and this unsteady phenomenon can seriously impact fan performance. Fan–distortion interaction is a highly unsteady aerodynamic ...
Comparative Studies of RANS Versus Large Eddy Simulation for Fan–Intake Interaction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present research applied a mixed-fidelity approach to examine the fan–intake interaction. Flow separation induced by a distortion generator (DG) is either resolved using large eddy simulation (LES) or modeled using the ...
Low Order Modeling for Fan and Outlet Guide Vanes in Aero-Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Intakes of reduced length have been proposed with the aim of producing aero-engines with higher efficiency and reduced weight. As the intake length decreases, it is expected that stronger effects of the fan on the flow ...
Numerical Analysis of an Instrumented Turbine Blade Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The measurement accuracy of the temperature/pressure probe mounted at the leading edge of a turbine/compressor blade is crucial for estimating the fuel consumption of a turbo-fan engine. Apart from the measurement error ...
Application of an Immersed Boundary Method on an Instrumented Turbine Blade With Large Eddy Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Leading edge instrumentation used in compressor and turbine blades for jet-engine test rigs can cause significant obstruction and lead to a marked increase in downstream pressure loss. Typical instrumentation used in such ...
