CFD model of computer chip

  1. Dec 8, 2008 #1
    I am running a CFD model with a computer chip measuring .06 x .05 x .005 m immersed in a rectangular duct measuring .3 x .1 x .02 m. The flow has velocity of about 2.5 m/s. The maximum temp. for the laminar case is about 440 K, while the max temp. for the turbulent case is 395 K. Does this sound right? I would have guessed the turbulent case would have a higher temp.
    Both cases have about the same average temperature (~310 K).

    turbulent boundary layer has enhanced mixing, & hence enhanced heat transfer coefficient.

    Take a look at the plot
