چکیده

Abstract The main aim of this article is to develop a new boundary element method (BEM) algorithm model and simulate the nonlinear thermal stresses problems in micropolar functionally graded anisotropic (FGA) composites with temperature-dependent properties. Some inside points are chosen treat terms domain integrals. An integral formulation which based on use Kirchhoff transformation firstly used simplify transient heat conduction governing equation. Then, residual carried out within current formulation. integrals can be effectively treated by applying Cartesian (CTM). In proposed BEM technique, temperature computed some integral. displacement calculated at each time step. With distributions, we obtain values stresses. efficiency our methodology has been improved using communication-avoiding versions Arnoldi (CA-Arnoldi) preconditioner for solving resulting linear systems arising from reduce iterations number computation time. numerical outcomes establish influence properties distribution, investigate effect parameter displacements stresses, through FGA These also confirm validity, precision effectiveness modeling simulation methodology.

Numerical Analysis of Transient Heat Transfer in Radial Porous Moving Fin with Temperature Dependent Thermal Properties

In this article, a time dependent partial differential equation is used to model the nonlinear boundary value problem describing heat transfer through a radial porous moving fin with rectangular profile. The study is performed by applying a numerical solver in MATLAB (pdepe), which is a centered finite difference scheme. The thermal conductivity and fin surface emissivity are linearly ...
