Asymptotic analysis and numerical modeling of mass transport in tubular structures

G. Cardone, G. P. Panasenko, Y. Sirakov

摘要:

本文研究了薄壁管结构中的流动问题。流动的速度代表在薄结构中设置的扩散-对流方程中的系数。构造了解的一个渐近展开。这种扩展进一步用于证明一个渐进的区域分解策略,基本上减少了内存和时间的代码。通过这种策略获得的数值解与通过直接有限元计算获得的数值解进行比较。

英文摘要:

In the paper the flow in a thin tubular structure is considered. The velocity of the flow stands for a coefficient in the diffusion-convection equation set in the thin structure. An asymptotic expansion of solution is constructed. This expansion is used further for justification of an asymptotic domain decomposition strategy essentially reducing the memory and the time of the code. A numerical solution obtained by this strategy is compared to the numerical solution obtained by a direct FEM computation.
