    • Experimental and computational investigations of a normal-hole bled supersonic boundary-layer 

      Oorebeek, JM; Babinsky, Holger; Ugolotti, M; Orkwis, P; Duncan, S (American Institute of Aeronautics and Astronautics, 2015-09-22)
      A series of experiments have been conducted on a bleed hole array spanning the width of the Cambridge University Engineering Department supersonic wind tunnel at Mach numbers of 1.8 and 2.5. The wind tunnel was run with ...
    • An Experimental Study on Truck Side-Skirt Flow 

      Stephens, RG; Babinsky, Holger (SAE International, 2016-04-05)
      The underbody of a truck is responsible for an appreciable portion of the vehicle’s aerodynamic drag, and thus its fuel consumption. This paper investigates experimentally the flow around side-skirts, a common underbody ...
    • Experiments and Computations on the Lift of Accelerating Flat Plates at Incidence 

      Stevens, Patrick Robert; Babinsky, Holger; Manar, F; Jones, AR; Nakata, T; Phillips, N; Bomphrey, RJ et al.
      This paper discusses the force history and flow topology of accelerating flat-plate wings. The work is a collaborative effort to study fundamental, unsteady low-Reynolds-number flows. The motion kinematics is designed to ...
    • Experiments to investigate lift production mechanisms on pitching flat plates 

      Stevens, PRRJ; Babinsky, Holger (Springer, 2017-01-01)
      © 2016, The Author(s).Pitching flat plates are a useful simplification of flapping wings, and their study can provide useful insights into unsteady force generation. Non-circulatory and circulatory lift producing mechanisms ...
    • Forces 

      Graham, William Richard; Pitt, Ford CW; Babinsky, Holger
    • An impulse-based approach to estimating forces in unsteady flow 

      Graham, William Richard; Pitt Ford, CW; Babinsky, Holger (Cambridge University Press, 2017-03-01)
      The ready availability of full-field velocity measurements in present-day experiments has kindled interest in using such data for force estimation, especially in situations where direct measurements are difficult. Among ...
    • Influence of boundary layer state on development downstream of normal shock interactions 

      Babinsky, Holger; Davidson, Todd
      Flat plate experiments investigating flow development downstream of normal shock wave–laminar boundary layer interactions are reported. Laminarity is desirable for low drag, but problems are expected at shock interactions ...
    • Raw PIV Images 

      Graham, William Richard; Pitt, Ford CW; Babinsky, Holger
    • Velocities 

      Graham, William Richard; Pitt, Ford CW; Babinsky, Holger
    • Vortical structures on three-dimensional shock control bumps 

      Colliss, SP; Babinsky, Holger; Nübler, K; Lutz, T (American Institute of Aeronautics and Astronautics, 2016-05-20)
      Three-dimensional shock control bumps have long been investigated for their promising wave drag reduction capability. However, a recently emerging application has been their deployment as “smart” vortex generators, which ...
