Turbulent flow in a square cross-section duct made of a 180o bend and two long straight inlet and outlet parts. 3D flow with constant temperature.
180o bend section connected to straight inlet and outlet tangents, all of square section: D × D = 88.9 × 88.9 mm. Centreline curvature radius of the bend: Rc = 3.357D.
Air at standard conditions.
The following measurements are available for the cross section located at z = -D. They correspond to a fully developed turbulent in a square section duct.
Contour maps as f(x,y) of:
Additional values of k and issued by numerical simulations are also available in the file input.
Velocity measurements using a rotatable hot-wire probe.
Analyzed but no published values.
