Abstract :
FLUID MAPPERS can be built to simulate a wide variety of electrostatic, magnetic, and other analogous fields. The visible flow pattern shows the field conformation in terms of a large number of flow lines. Some of these lines can be traced by being selected so that the tubes formed can be mapped by simple and sufficiently accurate routines. The flow pattern for the map of Figure 1 was formed using an 8- by 12-inch slab. Thirty-three lines, forming an equal number of tubes, were traced from the flow pattern. Line selection is arbitary, leading to a collection of unequal tubes. Only accidentally will the relative ohms of two of the tubes be the same.
