Shock Reflection at Interface of Bubbly Liquid

The reflection of a shock wave at a gas/liquid interface in a pipe is a design consideration in several industries. The transmitted and reflected shock pressures at a pure liquid interface can be six or more times as large as the initial shock, and creates proportionally large loads on the piping. Calculations shows that the magnitude of the transmitted and reflected shocks from the interface of a bubbly mixture is close to the same magnitude as if reflection occurred from a pure liquid interface, until the mixture void fraction is increased to nearly 90 percent, at which the mixture is becoming a froth.Copyright © 2008 by ASME
