Abstract: Everyone is familiar with the standard hydraulic jump observed when a jet hits a horizontal surface in the presence of gravity. However, surprisingly little is known about the shape of the hydraulic jump when a jet hits an inclined plane. We discuss a simple theory that predicts the rise height of such a jump. In the second part of the talk, we discuss the impact of a jet on a surface with bumps, and observe some surprising connections with Einstein’s theory of general relativity. This is joint work with Andrew Belmonte, Khalid Kamhawi, and Jay Johnson.
