Creating an air flow swirled by the Coriolis force using a two meter diameter pipe
The article describes an experiment conducted in 2016, proving the possibility of creating a swirled air flow due to the effect of the Coriolis force. A ventilator is located on the upper edge of a vertically installed pipe, creating an air updraft. Initially the air flow in the bottom part (between the lower edge of pipe and the horizontal underlaying surface) is of a radial character. But with the passage of time, due to the rotation of the Earth the air flow under the effect of the Coriolis force starts rotating in the bottom part in the positive direction since the experiment has been carried out in the Northern hemisphere. Definitive values of the pipe diameter and height, as well as of vertical air speed movement at which the values of circumferential velocity of air reach 1.6-1.8 m/s. The results of the experiment prove the propositions derived from the theoretical research of S.P. Bautin’s scientific school on the emergence of swirled air updrafts.
