Nonlinear phenomena are extremely important in space and solar plasma physics, as well as in other astrophysical systems. Spacecraft data analysis, numerical simulations and theoretical models are used and compared, to understand the physical processes occurring in such systems. Specific topics include phenomena related with turbulence and shocks in Astrophysical environments. Rayleigh-Taylor and Richtmyer-Meshkov instabilities and mixing are fundamental in many proceses. Techniques also need to be validated in turbulence; For example, new numerical and experimental techniques and observations. Direct numerical simulation, large-eddy simulation and turbulence models of compressible and hypersonic/hyperalfvenic flows. Mixing and Coherent structures in Astrophysical flows. Experimental, numerical and theoretical studies of instabilities and shocks. This session also collects contributions concerned with broad topics in nonlinear processes occurring in space, solar and astrophysical plasmas, such as turbulence, shock waves, magnetic driven flows, particle acceleration, dissipation mechanisms, etc.
