Abstract:Abstract: Chaotic mixing is of great significance for understanding the behavior of complex systems, improving the efficiency and quality of mixing processes, and promoting the development of science and technology. Through numerical simulation, the stirring effect of chaotic agitation is better than that of uniform agitation from the stirring track and flow field. Through the analysis of flow field trace, it is concluded that the basic reason of chaotic agitation to strengthen the stirring effect is that chaotic agitation breaks the isolation dead zone of agitation. At the same time, the chaos degree of the flow field generated by chaotic stirring is much greater than that of ordinary uniform stirring.
