ABSTRACT
In physical modelling a process of direct interest to the researcher is studied on a reduced model made from either the medium of full-scale or equivalent materials, while in mathematical modelling a system of differential equations describing such a process is studied and solved with the help of special analogue computers (ABM). The possibility of creating such ABM models is determined by similarity in mathematical description of a set of phenomena differing physically, that is, by the mathematical isomorphism of various physical systems. The merits of such computers, compared to digital computers of the discrete type, are low cost, relatively small dimensions and simple operation. The analogy method may be successfully employed for solving problems using computers or electrical network devices as well as in experimental investigation of processes on analogue machines, by the method of electro-hydrodynamic analogues.
