    Hello
    New member here looking for some specific info. In order to improve an air lift water pump I am looking to design or adapt a device to make air bubbles under water. The point is to reliably produce bubbles of a specific size for instance 30mm. The device must work the same with little or a lot of airflow.

    I have my own idea which invovles a sort of upside-down siphon but I'm wondering if there might be a simpler way. What about simply a cone shape(widest at the top) with the air injected at the bottom? If the walls are a shallow enough angle then I would have thought it was possible to create large bubbles and have them break at a specific point. In order to save alot of trial and error I was wondering if some clever people on here could do some sums to figure out a ballpark design that I can work off. Or if you have any better ideas I'm all ears.

    Thanks Adam

    Do you already know about the geyser pump?
    Airlift pump - Wikipedia, the free encyclopedia
    A recent (2007) variant called the "geyser pump" can pump with greater suction and less air. It also pumps proportionally to the air flow, permitting use in processes that require varying controlled flows. It arranges to store up the air, and release it in large bubbles that seal to the lift pipe, raising slugs of fluid.

    Hello Yes its a better geyser pump I am trying to create. I don't belive they make consistent bubbles.
