    Laminar VS Turbulent flow in a Wind Tunnel

    I am in the early design stages of building a small vertical wind tunnel for laboratory research of falling animal dynamics at terminal velocity. Although I have gone skydiving a few times, I am no expert. For all of you who are enthusiasts and I'm sure the couple of scientists out there too, I propose the following questions? What type of flow would best simulate a fall at terminal velocity, Laminar or Turbulent, why? Has anyone experienced time in a tunnel which has either extreme flow type or even experienced this in true free fall and noticed a difference in fall characteristics? Will either way make much of an impact on fall dynamics in the scheme of a 65 MPH terminal velocity? Feel free to get technical with fluid mechanics or however you may feel comfortable explaining for the non scientists, I appreciate all opinions. Greg
