Abstract: This paper investigates the blast wave mitigation performance of regular and particulate aqueous foams using shock tube experiments. Wet foam samples, with and without coal fly ash particles, were tested to examine shock wave reflection at the air foam interface, transmission into the foam column, and propagation within the foam during drainage. The results show that foam decay strongly affects reflected and transmitted wave behavior, while the addition of solid particles improves foam stability and alters shock propagation characteristics. Particulate foams reduced transmitted shock velocity by up to about 20% and maintained more uniform wave trajectories after longer drainage times compared with regular foams. The study also identifies double fronted pressure structures inside the foam, suggesting staged relaxation processes during shock interaction. Overall, the findings indicate that particulate aqueous foams can enhance blast wave attenuation by improving foam stability and delaying shock transmission.
