Off-design flow analysis of low-pressure steam turbines

Integrated Flow Control Devices for the Design of Enhanced Low Pressure Turbines

Flow separation limits the efficiency of low-pressure turbines (LPTs) in aircraft engines. Experiments with vortex generator jets (VGJs), conducted in AFRL's low-speed cascade at Wright-Patterson AFB, have demonstrated dramatic reductions in separation losses. The critical science that will enable this design innovation to reach its potential is a comprehensive understanding of the effect of VG...

Avoiding Stressed-Out Steam Turbines

assembly, Pro/ENGINEER CAD geometry was imported into ANSYS Mechanical software and meshed using SOLID185 elements. Frictionless surface-tosurface contact pairs with augmented Lagrangian algorithms were created between mating surfaces. A matching node pattern was maintained at the root and slot pressure faces, where load transfers take place between the two components. As an in-house design pra...

Steam Turbines for Biomass Plants

Power Plants, Steam and Gas Turbines WebQuest

A WebQuest is an Internet-based and inquiry-oriented learning activity. The aim of this work is to outline the creation of a WebQuest entitled “Power Generation Plants: Steam and Gas Turbines.” This is one of the topics covered in the course “Thermodynamics and Heat Transfer,” which is offered in the second year of Mechanical Engineering at the Defense University Center at the Naval Academy in ...
