Query: Bubble Collapse and Jet Formation in Corner Geometries   The collapse of a vapor bubble near a flat solid boundary results in the
formation of a jet that is directed towards the boundary. In more complex
geometries such as corners, predictions of the collapse cannot be made in a
straightforward manner due to the loss of axial symmetry. We experimentally
investigate the bubble collapse and jet formation in corners formed of two flat
solid boundaries with different opening angles. Using potential flow analysis,
we accurately predict the direction of the jet and bubble displacement. We
further show that for a corner with an opening angle $\alpha$, there exist
analytic solutions that predict the jet direction for all the cases
$\alpha=\pi/n$, where $n$ is a natural number. These solutions cover, in
discrete steps, the full range of corners from the limiting case of a bubble
near a single wall ($n=1$) up to a bubble in between parallel walls
($n\rightarrow\infty$).
