COMPUTATIONAL METHOD FOR THERMALLY COUPLED PROBLEMS BETWEEN COMPRESSIBLE-FLUID AND SOLID

An Iterative Substructuring Method for Coupled Fluid-Solid Acoustic Problems

A fast parallel iterative method is proposed for the solution of linear equations arizing from Finite Element discretization of the time harmonic coupled fluid-solid systems in fluid pressure and solid displacement formulation. The fluid and the solid domains are decomposed into nonoverlapping subdomains. Continuity of the solution is enforced by Lagrange multipliers. The system is augmented by...

Distributed Computational Method for Coupled Fluid Structure Thermal Interaction Applications*

The problem of effcient modeling and computation of the nonlinear interaction of fluid with a solid undergoing nonlinear deformation has remained a challenging problem in computational science and engineering. Direct numerical simulation of the non-linear equations, governing even the most simplified fluid-structure interaction model depends on the convergence of iterative solvers which in turn...

semi-analytical solution for static and forced vibration problems of laminated beams through smooth fundamental functions method

در این پایان نامه روش جدیدی مبتنی بر روش حل معادلات دیفرانسیل پارهای بر اساس روش توابع پایه برای حل مسایل ارتعاش اجباری واستاتیک تیرها و صفحات لایه ای ارایه شده است که می توان تفاوت این روش با روش های متداول توابع پایه را در استفاده از توابع هموار در ارضاء معادلات حاکم و شرایط مرزی دانست. در روش ارایه شده در این پایاننامه از معادله تعادل به عنوان معادله حاکم بر رفتار سیستم استفاده شده است که مو...

Iterative Solvers for Coupled Fluid-Solid Scattering

The multigrid method is used for coupled fluid-solid scattering discretized by linear finite elements. Numerical results show that using Krylov methods as smoothers allows coarser spaces than with standard smoothers, such as Jacobi and GaussSeidel. Block diagonal preconditioning for the 2 × 2 block diagonal matrix of the coupled system is also considered. Both multigrid and block diagonal preco...
