Spectral Properties Of Weakly Inhomogeneous Bcs-Models In Different Representations

Publikováno v: Zeitschrift für Naturforschung A. 60:343-365

For a class of Bardeen-Cooper-Schrieffer (BCS)-models, with complex, weakly momentum dependent interaction coefficients, the representation dependent effective Hamiltonians and their spectra are reconsidered in order to obtain a consistent physical p

An Empirical Prediction Method For Secondary Losses In Turbines—Part II: A New Secondary Loss Correlation

Autor: S. H. Moustapha, Michael Benner, S. A. Sjolander

Publikováno v: Journal of Turbomachinery. 128:281-291

A new empirical prediction method for design and off-design secondary losses in turbines has been developed. The empirical prediction method is based on a new loss breakdown scheme, and as discussed in Part I, the secondary loss definition in this ne

Experimental and Numerical Investigation of Corner Stall in a Highly-Loaded Compressor Cascade

Autor: Michael Benner, Yanfeng Zhang, Ali Mahallati

Publikováno v: Volume 2A: Turbomachinery.

Three-dimensional corner stall is one of the most important factors limiting compressor performance. This paper presents a complementary experimental and computational study of corner stall in a highly-loaded compressor cascade subjected to three inl

Flow control in an aggressive interturbine transition duct using low profile vortex generators

Autor: Michael Benner, Ali Mahallati, Yanfeng Zhang, Xue Feng Zhang, Shuzhen Hu, Edward Vlasic

This paper presents an experimental investigation of the flow mechanisms in an aggressive interturbine transition duct with and without low-profile vortex generators flow control. The interturbine duct had an area ratio of 1.53 and a mean rise angle

Flow control in an aggressive inter-turbine duct using low profile vortex generators

Autor: Michael Benner, Shuzhen Hu, Xue Feng Zhang, Yanfeng Zhang, Edward Vlasic

This paper presents the experimental investigation of the flow in an aggressive inter-turbine duct (AITD). The goal is to improve the understanding of the flow mechanisms within the AITD and of the underlying physics of lowprofile vortex generators (

Experimental and Numerical Study on an Inter-Turbine Duct

Autor: Michael Benner, Xue Feng Zhang, Edward Vlasic, Paul Gostelow, Shuzhen Hu

Publikováno v: Volume 7: Fluid Flow, Heat Transfer and Thermal Systems, Parts A and B.

The inter-turbine transition duct (ITD) between the high-pressure (HP) and low-pressure (LP) turbines of a gas turbine has the potential for significant length reduction and therefore engine weight reduction and/or aerodynamic performance improvement

Geometric Optimization of Aggressive Inter-Turbine Ducts

Autor: Michael Benner, Xue Feng Zhang, Shuzhen Hu, Paul Gostelow, Edward Vlasic

Publikováno v: Volume 7: Fluid Flow, Heat Transfer and Thermal Systems, Parts A and B.

To reduce the harmful effects of aviation on the environment, aircraft gas turbine manufacturers continue to focus on producing engines with lower specific fuel consumption and weight. To address the engine weight challenges, R&D efforts continue to
