Numerial Simulations Of Shock Waves On The Particle Interactions In 3D Complex Plasma

The development of traditional plasma matures,but due to its own nature,many aspects are difficult to achieve or further develop.Complex plasmas come into being,as a kind of plasma,in addition to the inclusion of electronic ions in the complex plasma particles,but also contains particles up to the order of microns.Because of their relatively large particle size,we can manipulate them and visualize them,providing a good study of a range of physical properties at the atomic level.Particles in the ground lab are affected by gravity,which can cause particles to pile up to the bottom.Although they can be partly offset by thermophoretic force,their effects are hard to eliminate.Therefore,the complex plasma experiment has been developed from the ground experiment to the experiment under the condition of space microgravity.The use of aircraft centrifugal force to offset the impact of gravity.PK-3 Plus,as a classic space station microgravity complex plasma experimental device,has been used for many years and sent back a large amount of data to the ground,promoting the development of complex plasma related research.However,many parameters of complex plasma experiments are difficult to measure and calculate,so the numerical simulation of microgravity complex plasma experiments plays an important role.Due to the controllable influence of parameters and strong adjustability,the numerical simulation can eliminate the influence of complicated factors and make the simulation results more accurate.It can provide a great reference for the analysis of experimental results.For the obvious phenomenon found in the experiment,further deep research can be conducted to help understand the experimental results.In this paper,we study the propagation of binary complex plasma waves on PK-3 Plus.In the past,most of the numerical simulations were focused on one or two levels,and there were many unary systems.In this dissertation,the research focused on the 3D numerical simulation.The main results of the numerical simulation on the shock reflection observed in the experiment were analyzed.The experimental understanding,at the same time,the impact of various parameters on shock wave propagation and interface phenomena.
