Homework Help: Reynolds Number Extended Essay Ideas?

  1. May 1, 2010 #1
    1. The problem statement, all variables and given/known data
    At the moment, I am planning my I.B extended essay (last 2 years at school), and have chosen to do my EE on physics. I've done loads of background research about Reynolds Number and how it affects the type of flow present.
    There is an experiment I can recreate (Reynolds experiment) where I change the speed of the water, and therefore Re and flow. However that alone is not EE worthy in terms of analysis.
    Is there any other experiments I could do that could give me a set of results I could analyze that relates to Re?


    2. Relevant equations
    I was also wondering, is there software where I could recreate / model ideal results of the experiment i.e a simulation?


    3. The attempt at a solution
    I thought about doing a second experiment where I could drop different objects into several fluids and see how with difference in viscosity the flow around the objects change. Alternatively have the fluid pumped by the objects? But in both cases I cant see how I could get data I could analyze.

    If you want a very good (and insanely expensive) program, I recommend COMSOL's Multiphysics. However, for the monetarily impaired, CSC's Elmer is an open-source (free) alternative that is less intuitive than COMSOL's program.
    Both require a good knowledge of CAD & Mesh generation, as well as the specific equations necessary to do the calculations (which can take minutes to days for calculations to complete, depending on the magnitude of the problem).

    Hope this helps.
