Description

The component DivergingTee 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 c to port st and port c to port s. Other flow directions are not supported.

Calculation of zeta is taken from Idelchik 'Handbook of Hydraulic Resistance', 4th Edition 2007, Diagram 7.18 and 7.20
