An experimental analysis on shock reflection over the two-dimensional model of a dust layer

Abstract
The shock reflection over a multi‐guttered wedge is investigated. The result is compared with the case with a dusty surface. It is found the wave structure is not self‐similiar but similar with respect to a nondimensional coordinate based on the pitch of gutters. The wave structure is essentially unsteady and the entire waves reflected from the bottoms of gutters play a key role to the configuration of reflected wave.
