Advanced Engineering Materials, EarlyView.Cermets (60 vol.% AISI 316L stainless steel, 40 vol.% recycled MgO), intended for use in aluminum electrolysis, were pre‐oxidized in three furnaces with different heating technologies and subjected to a cryolite corrosion test. The different atmospheres influenced the formation of oxide layers, which in turn affected corrosion resistance and ...

Parallel algorithm for numerical solution of heat equation in complex cylindrical domain
Discrete and Continuous Models and Applied Computational Science, 2019 In this article we present a parallel algorithm for simulation of the heat conduction process inside the so-called pulse cryogenic cell. This simulation is important for designing the device for portion injection of working gases into ionization chamber ...

The Initial Value Problem for the Equations of Magnetohydrodynamic Type in Non-Cylindrical Domain
Revista Matemática Complutense, 1995 Let \(r(t)\) be a positive-valued function of \(C^1[0, T]\), \[ Q= \{(x, t): x\in \mathbb{R}^n,\;0\leq t\leq T,\;(x)< r(t)\},\quad n= 2,3. \] The authors consider in domain \(Q\) the initial-boundary value problem \[ \begin{aligned} {\partial\overline u\over \partial t} & - {\eta\over \rho} \Delta\overline u+ (\overline u\cdot \nabla) \overline u- {\mu\

New energy effect in non-cylindrical domains with a thermally insulated moving boundary
Russian Technological Journal, 2023 Objectives. To develop mathematical model representations of the energy effect in non-cylindrical domains having a thermally insulated moving boundary; to introduce a new boundary condition for thermal insulation of a moving boundary both for locally equilibrium heat transfer processes in the framework of classical Fourier phenomenology, as well as for

Development of a methodology for collaborative control within a WEC array
International Marine Energy Journal, 2018 It has been established that Wave Energy Converters efficiency can be improved by control. One of the main challenges of reactive control is the non-causality of the optimal controller.

Dissipative Boussinesq equations on non-cylindrical domains in R^n
Electronic Journal of Differential Equations, 2010 This article concerns the initial-boundary value problem for the nonlinear Boussinesq equations on time dependent domains in $mathbb{R}^n$ with $1leq n leq 4$. Global solvability, uniqueness of solutions and the exponential decay to the energy are established provided the initial data are bounded in some sense.
