  • Experimental and computational investigation of an 'open' transonic cavity flow 
    Atvars, K.; Knowles, Kevin; Ritchie, S. A.; Lawson, Nicholas J. (Professional Engineering Publishing, 2009-06-30)
    This paper presents an investigation of a transonic flow (M∞=0.85) over a rectangular cavity having a length-to-depth ratio of 5. Velocities were measured inside the cavity on the central plane and two off-centre planes ...

    Atvars, K.; Knowles, Kevin; Ritchie, S. A.; Lawson, Nicholas J. (2009-11-10)
    This paper presents an investigation of a transonic flow (M∞ = 0.85) over a rectangular cavity having a length-to-depth ratio of 5. Velocities were measured inside the cavity on the central plane and two off-centre planes ...
  • Forcing boundary-layer transition on an inverted airfoil in ground effect 
    Roberts, L. S.; Finnis, Mark V.; Knowles, Kevin; Lawson, Nicholas J. (AIAA, 2017-07-21)
    The influence of the laminar boundary-layer state on a wing operating in ground effect has been investigated using experiments with a model that provides two-dimensional flow. The effect of a boundary-layer trip placed at ...
  • Forcing boundary-layer transition on an inverted airfoil in ground effect and at varying incidence 
    Roberts, L.; Finnis, Mark V.; Knowles, Kevin; Lawson, Nicholas J. (American Institute of Aeronautics and Astronautics Inc, AIAA, 2016-06-17)
    The influence of the laminar boundary-layer state on a wing operating in ground effect at Re = 6 × 10 has been investigated using experiments with a model that provides two-dimensional flow and computations with a panel-method ...
  • On the near-wake of a ground-effect diffuser with passive flow control 
    Ehirim, Obinna; Knowles, Kevin; Saddington, A. J.; Finnis, Mark V.; Lawson, Nicholas J. (Springer Verlag, 2019-02-08)
    A ground-effect diffuser is an upwardly-inclined section of an automobile’s underbody which increases aerodynamic performance by generating downforce. To understand the diffuser flow physics (force behaviour, surface and ...
  • Undercarriage drag prediction for a fixed undercarriage light aircraft 
    Bennett, Christopher J.; Gautrey, Jim; Lawson, Nicholas J. (AIAA, 2017-06-09)
    The following paper presents undercarriage drag predictions for a light aircraft with fixed landing gear. A Scottish Aviation Bulldog 120, operated by the National Flying Laboratory Centre (NFLC) at Cranfield University, ...
