RISEffect of Flow Distortions on Pin Fins in the Entry Region of Circular Channels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Utilizing heat transfer augmentation features at the inlet of aircraft engines as an additional heat sink requires further understanding of entry region heat transfer and flow field interactions. The effect of asymmetric ...
Endwall Loss and Mixing Analysis of a High Lift Low Pressure Turbine Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A high lift low pressure turbine (LPT) profile designated L2A is used as a test bed for studying the origin of endwall mixing loss and the role of vortical structures in loss development. It is shown analytically and ...
End Wall Loss Reduction of High Lift Low Pressure Turbine Airfoils Using Profile Contouring—Part II: Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The hypothesis, posed in Part I, that excessive end wall loss of high lift low pressure turbine (LPT) airfoils is due to the influence of high stagger angles on the end wall pressure distribution and not front loading is ...
