Conference paper


The effect of the passage of blast and shock waves over sand on a hard substrate as well as a hard pan was explored. While the initial entrainment by a blast wave is similar to that by a shock wave, there is a reduction in entrainment after the passage of the negative pressure phase which may reduce the overall estimate of entrained mass. Problems with apparatus and visualization mean that further tests will be required to develop meaningful quantitative data.



The results presented here were gathered by Ikhlaas Raoof and Neo Sambo as part of their undergraduate work.
