305 安定化気泡関数有限要素法を用いた熱流体-構造強連成解析

抄録

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.
