TL;DR: In this article, the lift and drag coefficients for a circular cylinder immersed in time dependent flow were analyzed using a potential flow model, and the results showed that the lift coefficients for the cylinder were linear in the length of the flow.

TL;DR: In this paper, the behavior of a variable viscosity jet of glass was studied analytically and experimentally, and the analytical predictions were found to be in error in the region of the jet within three to four nozzle diameters of the nozzle exit; below this point the theoretical and experimental results were in good agreement.
Abstract: To spin polymers or glass into continuous fibers, molten material is forced through a nozzle into air forming a free liquid jet. The jet is cooled as it proceeds through the air and the cold fiber is collected on a rotating drum. The drum maintains tension on the jet causing it to attenuate as it cools. The behavior of a variable viscosity jet of glass was studied analytically and experimentally. In the analysis, it was assumed that the velocity and temperature distributions within the jet were one dimensional. Predictions of the jet shape, the temperature distribution and the tension in the jet as a function of the material properties and the process variables were obtained. Measurements of the jet shape and the tension distribution in the jet were made for various values of the flow rate, the collecting drum speed, and the nozzle temperature. The analytical predictions were found to be in error in the region of the jet within three to four nozzle diameters of the nozzle exit; below this point the theoretical and experimental results were in good agreement.
TL;DR: In this article, the isotach pattern in a bounded jet with an aspect ratio of 6 suggests the presence of a secondary flow structure, and further measurements substantiate the model and support the conclusion that three-dimensional effects are highly significant in bounded jets of modest aspect ratio, even in the mid plane between the bounding walls.

TL;DR: In this paper, coupled oscillations of sloshing liquid in elastic rectangular and cylindrical tank, noting frequency changes due to level and container configuration were reported. But the authors did not specify the level and the container configuration.
