摘要：

New experimental and analytical results are reported for the problem of liquid drop shattering. Breakup is observed to occur as a result of the interaction between a drop and the convective flowfield established by the passage of a shock wave over it. The purpose of this investigation, which supplements and extends previous experimental and theoretical studies, is to establish the influence of various parameters on the rate of disintegration and on the time required for breakup to occur. Photographic, drop displacement, and break-up time information is presented for a range of conditions which involve shock waves moving at Mach numbers Ms = 1.5-3.5 in air over water drops having diameters of 750-4000μ. A model is formulated for the breakup phenomenon by considering that it results from a boundary-layer stripping mechanism. The experimental determination of the variation of drop shape and of drop velocity with time is used together with the analytical results to compute the disintegration rate. © 1969 American Institute of Aeronautics and Astronautics, Inc., All rights reserved.
