    NUMERICAL BENCHMARK PROBLEM 3.1: IDEALISED TEE-JUNCTION
    The purpose of this problem is to test of the ability
    of computational procedures to calculate the separation
    of a lighter from heavier phase when a lateral pressure
    gradient is induced by the presence of an aperture in
    the side of a duct.

    Phenomena of this kind make their appearence whenever
    a two-phase mixture flowing in a pipe is allowed to
    escape through a break in the pipe wall. In that case,
    the flow pattern is bound to be three-dimensional;
    but a two-dimensional problem is here regarded as
    being both sufficiently illuminating and sufficiently
    difficult.
