Calculation of actual spray angle and coverage

  1. Sep 30, 2015 #1

    I am attempting to figure out the optimal nozzle placement for an evaporative cooling tower. Now, calculating the theoretical coverage of each nozzle is obviously not a problem since I know the spray angle of the nozzles. However, since the water is injected at a much higher speed than the gas (Co-current), I am assuming that drag forces will play an important part and the actual coverage of each nozzle will be smaller.

    I would like to be able to calculate the actual coverage of the nozzle at any given distance from it.

    I know the size of the droplets, the velocity and density of both the gas and the water.

    Any help on how to solve this mathematically is greatly appreiated

    I don't know anything about cooling towers but I'm wondering how do you know the spray angles and drop sizes? I did some spray coverage stuff for pressure control in reactor containment buildings and it was all based on spray nozzle tests done by the nozzle vendor.
