Shifted periodic boundary conditions for simulations of wall-bounded turbulent flows

open access: yesPhysics of Fluids, 2016
In wall-bounded turbulent flow simulations, periodic boundary conditions combined with insufficiently long domains lead to persistent spanwise locking of large-scale turbulent structures.

Non-classical periodic boundary value problems with impulsive conditions

open access: yesJournal of New Results in Science, 2023
This study investigates some spectral properties of a new type of periodic Sturm-Liouville problem. The problem under consideration differs from the classical ones in that the differential equation is given on two disjoint segments that have a common end,
