Thermal-Fluid Structure Strong Interaction Analysis Using Stabilized Bubble Function Finite Element Method

Abstract

For the purpose of the improvement in efficiency and stability and accuracy of the calculation, spatial discretization is applied to the mixed interpolations for the velocity and pressure fields by the stabilized bubble element and linear element, respectively. This paper presents a finite element analysis of a thermal-fluid structure interaction problem, in which the fluid is treaded as incompressible viscous flow with boussinesq approximation, and a structure is idealized by elastic springs.
