| 摘要： | Blast-induced droplet breakup energy absorption and vaporization time scales were estimated for the fragmentation of a 0.5 mm parent droplet into 20 micrometer mono-dispersed droplets. The energy extraction from vaporization was found to be more significant in weakening the shock as compared to droplet breakup energy extraction. The efficiency of the droplet breakup process proved to be critical in increasing the total surface area of the ultra-fine mist (UFM) generated. A 22-fold increase in surface area of the 20 micrometer droplets reduces vaporization time scales, giving the droplets a faster response to shock energy extraction by latent heat absorption. / NOTE:Memorandum rept. |
