title = "Nonlinear development of the multiple G{\"o}rtler modes in hypersonic boundary layer flows",
abstract = "The linear and nonlinear development of the G{\"o}rtler vortices in hypersonic boundary layer flows with the consideration of multi-G{\"o}rtler-modes are investigated using the normal mode analysis and the parabolized stability equations. The linear local analysis predicted the crossover of the multiple G{\"o}rtler modes (between the trapped-layer mode and the primary wall-layer mode) when the G{\"o}rtler number and Mach number are large enough, e.g. Ma≥4, G>2000. The Ma=4 case is verified with the linear marching analysis. Five particular regions can be distinguished depending on the behavior of the multi modes. The nonlinear analysis is performed for a Ma=6 case proposed by Li et al.1 The saturation of the disturbances is reached and the mushroom structures are generated. The multi-modecrossover is also observed with nonlinear effects.",
