Description
The component ConvergingTee is a specialized element that works only in a narrow boundary condition. It represents a 90° T-branch with equal diameter for main passage (sides c and st) and any diameter for branch s.
The flow direction is mandantory and has to be from port st to port c and port s to port c. Other flow directions are not supported.
Calculation of zeta is taken from Idelchik 'Handbook of Hydraulic Resistance', 4th Edition 2007, Diagram 7.4
