摘要

The flow of a fluid through the whole of a structure is easily analyzed by a process that comprises separating and dividing the computation of flow along the course of the fluid flowing in the structure and superpositioning the results of analysis. The fluid flow analyzing system used for this analysis is furnished with a fluid flow analyzing step that comprises subjecting the flow induced in the structure by the fluid flowing in the structure to analytical computation with a computer by using the following linear equation and obtaining the result of this analysis. $$ \begin{array}{cc}\frac{{\partial }^2\Phi }{\partial x^2}+\frac{{\partial }^2\Phi }{\partial y^2}+\frac{{\partial }^2\Phi }{\partial z^2}=0& \mathrm{Formula}\left(1\right)\end{array}$$;The analytical computation is carried out in the sequence of steps shown in FIG. 8.
