Whats the best fluid model to use for water?

  1. May 15, 2009 #1
    I realize this seems basic, but I'm looking around on the net and i just cant find the answer. I'm running a ANSYS simulation of heat transfer through a pipe and I was using a Newtonian model, but then someone mentioned about using the power model. I cant seem to find the definitive answer as to which is best. The flow is in the transition Reynolds flow regime between 56F and 112F on the tube wall.
    thanks

    If you are still working on this, are you using ANSYS traditional or Work Bench? What is the pipe material?

    Thanks
    Matt
