O článku:
The complexity of flow conditions at junctions amplifies significantly with supercritical flow. It is a pronounced
three-dimensional two-phased flow phenomenon, where standing waves with non-stationary water surface are
formed. To analyse the hydrodynamic conditions at an asymmetric right-angled junction with incoming supercritical
flows at Froude numbers between 2 and 12, an experimental approach was used. For a phenomenological determination
of the relations between the integral parameters of incoming flows and the characteristics of standing waves at the junction
area, water surface topographies for 168 scenarios at the junction were measured using non-intrusive measurement
techniques. The new, phenomenologically derived equations allow for determination of location, height and extent of the
main standing waves at the junction. Research results give important information on the processes and their magnitude
for engineering applications.
