Riblets as a Viscous Drag Reduction Technique
- M. J. Walsh
- Physics
- 1 April 1983
T viscous drag of turbulent boundary layers is a significant factor contributing to the fuel costs of the airlines. Several studies have indicated that microsurface geometry variations which change… Expand
Design challenges and analysis of the ITER core LIDAR Thomson scattering system
- M. J. Walsh, M. Beurskens, +7 authors C. Walker
- Physics
- 19 October 2006
The maximum temperature expected in ITER is in the region of 40keV and the minimum average density of approximately 3×1019m−3 is also expected. The proven capability, convenience, and port occupancy… Expand
Effect of detailed surface geometry on riblet drag reduction performance
- M. J. Walsh
- Engineering
- 1 June 1990
A comparison is made of the effect of small changes in v-groove geometry, for several riblet films applicable for drag reduction to commercial transport aircraft, whose nominal v-groove dimension is… Expand
Fatigue crack propagation of coplanar semi-elliptical cracks in pure bending
- W. Soboyejo, J. Knott, M. J. Walsh, K. R. Cropper
- Materials Science
- 1990
Abstract The first part of this paper presents stress intensity factor solutions for coalescing coplanar semi-elliptical cracks subjected to pure bending. Crack shapes of “beachmarked” test pieces… Expand
ELM characteristics in MAST
- A. Kirk, G. Counsell, +12 authors Y. Yang
- Materials Science
- 1 March 2004
Edge localized mode (ELM) characteristics in a large spherical tokamak (ST) with significant auxiliary heating are explored. High confinement is achieved in mega ampere spherical tokamak (MAST) at… Expand
Near‐field photothermal microspectroscopy for adult stem‐cell identification and characterization
- Olaug Grude, A. Hammiche, +4 authors N. Fullwood
- Chemistry, Medicine
- Journal of microscopy
- 1 December 2007
The identification of stem cells in adult tissue is a challenging problem in biomedicine. Currently, stem cells are identified by individual epitopes, which are generally tissue specific. The… Expand
Comparative assessment of dissipated energy and other fatigue criteria
- A. Korsunsky, D. Dini, F. Dunne, M. J. Walsh
- Materials Science
- 1 September 2007
Abstract Amongst a large number of fatigue criteria proposed for the prediction of crack initiation in thermo-mechanical fatigue, various approaches have been found to be particularly useful for… Expand
On the Effect of Atomic Structure on the Activity and Deactivation of Catalytic Gold Nanoparticles
- M. J. Walsh, K. Yoshida, Mungo Pay, P. Gai, E. Boyes
- Materials Science
- 1 October 2012
We present studies of the structure and stability of catalytic gold nanoparticles through in situ aberration‐corrected electron microscopy to investigate the effect of heating on the nature of the… Expand
In-situ heating studies of gold nanoparticles in an aberration corrected transmission electron microscope
- M. J. Walsh, K. Yoshida, P. Gai, E. Boyes
- Materials Science
- 1 July 2010
Gold nanoparticles have a high catalytic activity for CO oxidation at low temperatures providing they remain less than 5nm in diameter. Their structure and stability and the growth processes that… Expand
