A dispersive wave hydro-sediment-morphodynamic model developed by complementing the shallow water (SHSM) equations with term from Green–Naghdi is presented. numerical solution algorithm for based on second-order Strang operator splitting The partitioned into two parts, (1) SHSM and (2) correction part, which are discretized using discontinuous Galerkin finite element methods. This technique pro...

On the basis of analysis thermoelastic motion, current research develops a novel model modified thermoelasticity. The rotating long hollow cylinders with fixed surfaces are considered in generalized Moore–Gibson–Thompson (MGTTE) framework, including Ohm’s law. made material that rotates at uniform rotational speed and is elastic transverse direction. set equations for MGT heat conduction new bu...

In this paper, a new analysis of thermoelastic, homogeneous, and isotropic nanobeams has been constructed in the context Green-Naghdi type-II heat conduction law. The first end nanobeam is based on graphene strip, which contains an electrical current with small voltage novel application. Under simply supported boundary conditions fixed side ratios, thermally loaded source due to thermal effect ...

In this work, we numerically consider a thermoelastic problem where the thermal law is modeled using so-called Moore–Gibson–Thompson equation. This thermomechanical written as coupled system composed of hyperbolic partial differential equation for transformation displacement field and parabolic temperature. Its variational formulation in terms derivatives above transformed functions, leading to...

This paper derives an averaged Lagrangian functional for dynamic coupling between rigid-body motion and its interior shallow-water sloshing in three-dimensional rotating translating coordinates; with a time-dependent rotation vector. A new set of variational equations (SWEs) generalized Green–Naghdi the fluid 3-D vector translations, also linear momentum angular containing shallow water, are de...

A dispersive wave hydro-morphodynamic model coupling the Green–Naghdi equations (the hydrodynamic part) with sediment continuity Exner equation morphodynamic is presented. Numerical solution algorithms based on discontinuous Galerkin finite element discretizations of are proposed. The include both coupled and decoupled approaches for solving parts simultaneously separately from each other, resp...

Abstract In this note, we study the optimal control of a nonisothermal phase field system Cahn–Hilliard type that constitutes an extension classical Caginalp model for transitions with conserved order parameter. The couples equation source term parameter universal balance law internal energy. place standard Fourier form, constitutive heat flux is assumed in form given by theory developed Green ...

Green information systems is increasingly gaining appeal as a mechanism for firms to balance financial performance and environmental sustainability goals. We argue, however, that, the role of green IS practices has been under conceptualized in the green IS literature. This paper takes a practice theory view, using structurational theory, to re-conceptualize the green IS phenomenon through a pra...

We are interested in the modeling of wave-current interactions around surf zones at beaches. Any model that aims to predict the onset of wave breaking at the breaker line needs to capture both the nonlinearity of the wave and its dispersion. We have therefore formulated the Hamilto5 nian dynamics of a new water wave model, incorporating both the shallow water and pure potential flow water wave ...
