Scaling Three Dimensional Low Pressure Turbine Blades for Low Speed Testing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present activity was carried out in the framework of the Clean Sky European Research Project ITURB (optimal highlift turbine blade aeromechanical design), aimed at designing and validating a turbine blade for a geared ...
A Path Toward the Aerodynamic Robust Design of Low Pressure Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Airline companies are continuously demanding lowerfuelconsuming engines and this leads to investigating innovative configurations and to further improving single module performance. In this framework the low pressure turbine ...
Accounting for Unsteady Interaction in Transonic Stages
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper discusses the importance of the unsteady interaction in transonic turbomachinery stages. Although the flow in a turbomachine is inherently unsteady, most current calculations for routine design work exploit the ...
Secondary Flows in Low-Pressure Turbines Cascades: Numerical and Experimental Investigation of the Impact of the Inner Part of the Boundary Layer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to the low level of profile losses reached in low-pressure turbines (LPT) for turbofan applications, a renewed interest is devoted to other sources of loss, e.g., secondary losses. At the same time, the adoption of ...
Capturing Radial Mixing in Axial Compressors With Computational Fluid Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The current industrial standard for numerical simulations of axial compressors is the steady Reynolds-averaged Navier–Stokes (RANS) approach. Besides the well-known limitations of mixing planes, namely their inherent ...
Analysis of the Loss Production Mechanism Due to Cavity–Main Flow Interaction in a Low-Pressure Turbine Stage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the present work, URANS simulations are presented to describe the unsteady interaction process between the flow ingested/ejected from a cavity system and the main flow evolving into a low-pressure turbine stage. Particular ...
