When modeled within the unsteady Reynolds-averaged Navier–Stokes framework, shock wave dynamics on a two-dimensional airfoil at transonic buffet conditions is characterized by time-periodic oscillations. Given time series of lift coefficient different angles attack for OAT15A supercritical profile, Sparse Identification Nonlinear Dynamics (SINDy) technique used to extract parameterized, interpr...

In this paper we carry on the study of a system recently introduced by first author as planar version well known electrostatic Schrödinger–Maxwell equations. positive potential case, exhibit situations where existence solutions depends strength coupling, being one modulated parameter. We also present some results in case sign-changing potential.

r. ewing, o. liev, r. lazarov and a. naumovich in [1] proposed a finite volume discretization for one dimensional biot poroelasticity system in multilayer domains. their discretization and exact solution are invalid. we derive valid discretization and exact solution. finally, our numerical solution is compared with known exact solution in discrete l2 norm.
