Description

This study investigates the applicability of the symbolic data processing program to the various kinds of problems in fluid mechanics and examines its possibilities. As a link of the chain of this study, we take up the dimensional analysis using the pi theorem and develop the system written in LISP, which helps human intelligence analyze physical phenomena by the pi theorem. Some features of this system are as follows : The dimensions of the physical quantities have been put in the storage of the system in advance. When a physical quantity is input, the system gets into dimensions from the storage. This saves the difficulty of the input. The existing quantities, such as the Reynolds number and the Nusselt number have also been placed in the storage. When the pi numbers obtained by the pi theorem need the rewriting or when the physical meaning of the pi numbers is required the system refers to the existing quantities in the storage and imparts instruction.
