Mathematical models of nonlinear longitudinal-cross oscillations of object with moving borders

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2015
The nonlinear formulation of problems for describing longitudinal-cross oscillations of objects with moving borders is noted. These mathematical models consist of a system of two nonlinear partial differential equations with the higher time derivative of

To the solution of the Solonnikov-Fasano problem with boundary moving on arbitrary law x = γ(t).

Қарағанды университетінің хабаршысы. Математика сериясы, 2021
In this paper we study the solvability of the boundary value problem for the heat equation in a domain that degenerates into a point at the initial moment of time. In this case, the boundary changing with time moves according to an arbitrary law x = γ(t)

Moving boundary problems with Ermakov symmetry reduction: nonlinear superposition principle and reciprocal transformation applications [PDF]

Open Communications in Nonlinear Mathematical Physics
Moving boundary problems of Stefan-type for a novel third order nonlinear evolution equation with temporal modulation are here shown to be amenable to exact Airy-type solution via a classical Ermakov equation with its admitted nonlinear superposition ...

Radially Symmetrical Heat Hydrate Dissociation Model with a Density Difference

Energies, 2022
The hydrate dissociation is viewed as a phase change process in which hydrates transform from a solid phase into gas and liquid phase at a moving dissociation boundary.

Moving and reactive boundary conditions in moving-mesh hydrodynamics [PDF]

Monthly Notices of the Royal Astronomical Society, 2020
ABSTRACT We outline the methodology of implementing moving boundary conditions into the moving-mesh code manga. The motion of our boundaries is reactive to hydrodynamic and gravitational forces. We discuss the hydrodynamics of a moving boundary as well as the modifications to our hydrodynamic and gravity solvers.
