Under a skimming flow regime, water flows in a coherent stream down the step. Water skims the top of each step as it flows down the chute.
WebJan 1, 2011 · Fully nonlinear solutions of free surface flow under a sluice gate are presented in this paper. The fluid upstream is assumed to be infinitely in depth, and it flows under the gate forming... In physics, a free surface is the surface of a fluid that is subject to zero parallel shear stress, such as the interface between two homogeneous fluids. An example of two such homogeneous fluids would be a body of water (liquid) and the air in the Earth's atmosphere (gas mixture). Unlike liquids, gases cannot … See more Flatness refers to the shape of a liquid's free surface. On Earth, the flatness of a liquid is a function of the curvature of the planet, and from trigonometry, can be found to deviate from true flatness by approximately 19.6 See more If the free surface of a liquid is disturbed, waves are produced on the surface. These waves are not elastic waves due to any elastic force; they are gravity waves caused by the force of gravity tending to bring the surface of the disturbed liquid back to its horizontal level.
