| Simon THALABARD (InPhyNi) | | Self-similar blowups in cascade fluid models | | The blowup problem in mathematical fluid dynamics addresses the settlement of non-Lipschitz singularities within a finite-time horizon, out of sufficiently smooth initial data. One of the simplest scenarios is that of asymptotic self-similarity, which describes the finite-time algebraic convergence towards a universal self-similar profile, prescribed as a non-linear eigenvalue problem. Examples of self-similar blowups are found in the simplified setting of cascade models, including in particular diffusive approximations and shell-representations of fluid dynamics. In these local dynamics, I will discuss insights from various numerical strategies addressing the underlying non-linear eigenvalue problem, from shell-time renormalization scheme to bifurcation theory and brute-force optimization. | | Gestion: Joris |
