The impingement and evaporation of the H2O/n-Al nanofluid droplet with ammonium perchlorate (AP) particles is fundamental process in preparation core-shell structure via a fluidized bed. In this work, spreading dynamics impact on heated aluminum (Al) surfaces have been investigated experimentally using high-speed photography. It has demonstrated that addition high concentration n-Al improved diameter droplets impacting solid surfaces, increased pinning time, decreased rate. Shell formation collapse phenomena were observed for Al surface inhibited AP surface. time an shorter at higher Weber number because heat transfer area due to larger contact area. was found be more complex hygroscopic nature AP, which enhances liquid immersion affects characteristics. All liquids immersed within 2 s, approximately 100 times than same temperature number. Nonlinear volume change during caused by simultaneous current findings provide new insights into understanding novel structures such as AP@Al.
