Surface impedance water layer in partially filled cavities

  1. Dec 6, 2015 #1
    Hello guys!

    I have to model the acouctic field within partially filled cavities.

    So consider a rectangular or cylindrical cavity that is partially filled with water. I would like to model the water layer as a sound absorbing wall by prescribing it as a surface impedance boundary condition.

    My problem is modelling the surface impedance of water. Are there any standard surface impedance models for fluids like water? Or how should I model the surface impedance for water?

    I'm also open for any other suggestions in approaching the water layer as a sound absorbing wall.

    Thanks for your answers!

    I would guess that the water is intended to be a perfect reflector and not an absorber.

    Do you think the absorbence is small to neglect?
