A Study of Large Tip Clearance Flows in an Axial Compressor Cascade (2006)
Presentation / Conference Contribution
Gregory-Smith, D., Williams, R., & He, L. (2006, May). A Study of Large Tip Clearance Flows in an Axial Compressor Cascade. Presented at ASME turbo expo : power for land, sea, and air 2006, Barcelona, Spain

The tip clearance flow of industrial axial compressor rotors has a significant impact on compressor performance. Most tip clearance flow research work has been undertaken in the earlier low-pressure transonic stages of compressors. The main differenc...

An experimental study of reverse compound lean in a linear turbine cascade (2005)
Journal Article
Bagshaw, D., Ingram, G., Gregory-Smith, D., & Stokes, M. (2005). An experimental study of reverse compound lean in a linear turbine cascade. Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 219(6), 443-449. https://doi.org/10.1243/095765005x31199

This paper describes a detailed experimental investigation into the effects of reverse compound lean (RCL) in a highly loaded axial turbine cascade. The geometry was designed using fully three-dimensional viscous CFD calculations to achieve a reducti... Read More about An experimental study of reverse compound lean in a linear turbine cascade.

Investigation of a novel secondary flow feature in a turbine cascade with end wall profiling (2005)
Journal Article
Ingram, G., Gregory-Smith, D., & Harvey, N. (2005). Investigation of a novel secondary flow feature in a turbine cascade with end wall profiling. Journal of Turbomachinery, 127(1), 209-214. https://doi.org/10.1115/1.1812321

A novel secondary flow feature, previously unreported for turbine blading as far as the authors are aware, has been discovered. It has been found that it is possible to separate part of the inlet boundary layer on the blade row end wall as it is bein...

A new infinite element for unbounded water wave problems (2003)
Journal Article
Baghbani, A., & Gregory-Smith, D. (2003). A new infinite element for unbounded water wave problems. Applied Ocean Research, 25(4), 213-223. https://doi.org/10.1016/j.apor.2004.02.001

A new mapped infinite wave envelope element is developed to model two-dimensional unbounded water wave problems in conjunction with wave finite elements. The infinite elements may be used on the exterior of an ellipse or other shapes. Examples are im... Read More about A new infinite element for unbounded water wave problems.

A Design Method for the Profiling of End Walls in Turbines (2002)
Presentation / Conference Contribution
Gregory-Smith, D., & Hartland, J. (2002, June). A Design Method for the Profiling of End Walls in Turbines. Presented at ASME turbo expo 2002 : land, sea and air, Amsterdam, The Netherlands

The profiling of end walls in turbines has proved to be effective in reducing secondary flows and losses in turbines, both in cascades and in a turbine representative rig. This paper presents a simple method for the design of end walls using the phil... Read More about A Design Method for the Profiling of End Walls in Turbines.

The effect of end-wall profiling on secondary flow and loss development in a turbine cascade (2002)
Presentation / Conference Contribution
Ingram, G., Gregory-Smith, D., Rose, M., Harvey, N., & Brennan, G. (2002, June). The effect of end-wall profiling on secondary flow and loss development in a turbine cascade. Presented at ASME Turbo Expo 2002 : land, sea and air (GT2002)., Amsterdam, The Netherlands

The potential for loss reduction by using non-axisymmetric end-wall profiling has been demonstrated in the so called “Durham” cascade (Hartland et al [1]) and in a turbine representative rig (Brennan et al [2] and Rose et al [3]). This paper aim to e... Read More about The effect of end-wall profiling on secondary flow and loss development in a turbine cascade.

Prediction of Turbomachinery Flow Physics from CFD - Review of Recent Computations of APPACET Test Cases (2001)
Journal Article
Gregory-Smith, D., & Crossland, S. (2001). Prediction of Turbomachinery Flow Physics from CFD - Review of Recent Computations of APPACET Test Cases. T.A.S.K. Quarterly, 5(4), 407-432

In order to maintain a competitive edge, the turbomachinery industry has to rely increasingly on design and analysis methods based on numerical simulation of flow. The European funded APPACET was set up to study the application of turbulence modellin...

Non-axisymmetric turbine end wall profiling (2001)
Journal Article
Gregory-Smith, D., Ingram, G., Jayaraman, P., Harvey, N., & Rose, M. (2001). Non-axisymmetric turbine end wall profiling. Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 215(6), 721-734. https://doi.org/10.1243/0957650011539027

A design method for profiling the end wall to reduce secondary flow has been reported previously. A profile has been tested in the Durham Linear Cascade and the results confirmed the design method. This paper describes the design and testing of a sec... Read More about Non-axisymmetric turbine end wall profiling.
