Abstract Scope |
The deagglomeration of carbon nanotubes (CNTs) to successfully manufacture metal matrix composites (MMCs) is a complex problem. The first step of this process is to achieve a well-mixed suspension of CNTs breaking up and dispersing clusters. Ultrasonic treatment (UST) has been shown to deagglomerate and disperse CNTs in various liquids but there is not a full understanding of the process. Here we report on modelling of some high speed imaging experiments of the deagglomeration and dispersal of CNTs in water. Experimental data has shown breakup of CNTs, flow and bubble dynamics. Our modelling demonstrates the flow and differences in the bubble dynamics for different surface tensions caused by the addition of surfactants. We will focus on the numerical results validated by the experimental data. These numerical results have the potential to be applied in future to liquid metals where in situ experiments are more complex. |
