Buckling of a turbulent jet surrounded by a highly flexible duct

An experimental and theoretical study of the static buckling of a downward flowing stream surrounded by a highly flexible duct is reported. It is shown analytically that the stream buckles into a meandering shape that depends strongly on the flow velocity in the duct. The amplitude of the buckled shape is found to be governed by the magnitude of the transverse force created by nonzero curvature at the free end of the duct. Experimental measurements confirm the buckled shape described analytically. © 1983 American Institute of Physics.
