A Entrainment Coefficient - Dynamics of Fluids

  1. May 11, 2017 #1
    Hi all,

    i ask in advance sorry for my bad english, i hope you will understand my question.

    I'm studying the motion of a plume fluid in a fluid ambient, with ρ(plume) > ρ(ambient).
    Afterwards there si a transport of fluid ambient as an effect of the turbolence caused by the viscosity between the two fluids.
    This is, somehow, featured by the Alpha coefficient (entrainment)

    My request is: can you explane to me, what physically represent this number? What i have to imagine when i want to figure out the entrainment? Wich is the formule?

    Thank for your time!
