The stilling section of the wind tunnel is divided into two independent sections by a splitter plate.
Communication of the unsteady pressures to the stilling chamber was noted.
The upstream stilling tank contained a perforated plate followed by a screen and open-cell sponge section, and a smooth two-dimensional contraction a t the outlet.
Some show brief lapses in awareness and orientation by freezing or stilling, for example.
Discharge was controlled independently of the swirl vanes with a motoroperated cone valve at the upstream end of the stilling chamber.
At each end of the test section there was a large stilling tank to isolate the test section from any hydrodynamic disturbances in the flow loop.
The structures have included intakes, sluices, spillways and stilling basins.
However, one word calls out to me from page after page of the report, stilling those voices of passion.
