I Forced convection over a cylinder

  1. May 10, 2017 #1
    I am building an apparatus to measure how does fluid speed effect heat transfer from solid on fluid. fluid runs over a cylinder which inner side is kept at a constant temperature. A calculation for surface temperature profile was made for a similar eaxperiment were a flat plate was used instead of a cylinder. I would like to ask weather it is safe to use the same correlation between the nuslet number and reynolds number:
    Nu=C/m * Re˘m * Pr˘n
    where C = 0.332, m = 1/2 and n = 1/3 for a laminar boundary layer
    and C = 0.0287, m = 4/5, n = 3/5 for a turbulent boundary layer
    and therefore if calculations for surface temperature profile calculations made for flat plate alo apply for cylinder.
    Thank you for your answers

    What do you think and why?
