RISUpdating Turbomachinery Aerodynamics Teaching on an Undergraduate Course Using Three-Dimensional Design Tools
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper outlines the update of a turbomachinery course to cover three-dimensional (3D) aerodynamics using a Reynolds-Averaged Navier Stokes solver. Prior to the activities outlined in this paper, the course was taught ...
The Influence of Inlet Asymmetry on Steam Turbine Exhaust Hood Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It has been widely recognized for some decades that it is essential to accurately represent the strong coupling between the last stage blades (LSB) and the diffuser inlet, in order to correctly capture the flow through the ...
Efficient Methods for Predicting Low Pressure Steam Turbine Exhaust Hood and Diffuser Flows at Design and Off Design Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The exhaust hood of a steam turbine is an important area of turbomachinery research as its performance strongly influences the power output of the last stage blades (LSB). This paper compares results from 3D simulations ...
A Literature Review of Low Pressure Steam Turbine Exhaust Hood and Diffuser Studies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper summarizes the findings from research studies carried out over the last 30 years, to better understand the flows in steam turbine low pressure exhaust hoods and diffusers. The work aims to highlight the areas ...
The Physics of H Darrieus Turbine Starting Behavior
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper provides a resolution to the contradictory accounts of whether or not the Darrieus turbine can selfstart. The paper builds on previous work proposing an analogy between the aerofoil in Darrieus motion and ...
