  • Aerodynamics of a convex bump on a ground-effect diffuser 
    Ehirim, Obinna; Knowles, Kevin; Saddington, A. J.; Finnis, Mark V. (Journal of Fluids Engineering, 2018-04-19)
    A ground-effect diffuser is an upward-sloping section of the underbody of a racing car that enhances aerodynamic performance by increasing the downforce, thus improving tire grip. The downforce generated by a diffuser can ...
  • 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 ...
  • Passive flow control on a ground-effect diffuser using an inverted wing 
    Ehirim, Obinna; Knowles, Kevin; Saddington, A. J.; Finnis, Mark V. (SAE, 2018-08-13)
    In this experimental and computational study a novel application of aerodynamic principles in altering the pressure recovery behavior of an automotive-type ground-effect diffuser was investigated as a means of enhancing ...
