Turbulent flow of meandering duct with square cross section

Note: Figures are shown on half cross section, considering calculated object.

Numerical object and computational mesh
Meandering duct consists of three 180゜ curved ducts.

Stramwise velocity
The flow runs to right side outlet from left side inlet.
