Research Question Relating to Airflow and Airfoils

  1. May 3, 2009 #1
    I am currently a junior in high school in the full I.B. program and I am developing a research question for an extended essay. I have chosen to write an essay in the field of physics, and more specifically, aerodynamics.

    At the moment, I am trying to conceptualize a working research question that would involve a practical experiment. Furthermore, I am a pilot, so I understand some basic aerodynamic phenomena.

    The following topics are possibilities that I am working on:

    1) The effect of the shape of an airfoil on the ground effect phenomenon.

    2) The effect of the shape of an airfoil on wind shear.

    3) Variations in wake for spheres of differing shapes (possibly and experiment with a smooth sphere and a golf ball). (This site focuses on this idea: http://www.aerospaceweb.org/question/aerodynamics/q0215.shtml")

    4) How the placement of the "hump" on aircraft wings affect laminar flow and drag (similar to question number 3 on this post: https://www.physicsforums.com/showthread.php?t=305213&highlight=Aerodynamics")

    Now, I am stuck at this stage. I am wondering which question is most practical to use as a research question. (Ideally, this essay would involve an experiment using a wind tunnel.)

    I am looking for help either eliminating possible topics, tweaking topics or focusing topics. I am in a brainstorming stage still, so any ideas could be helpful.

    Thank you
