Resurrecting the Electrolytic Plotting TankAbstract:Before the advent of CFD software, electrolytic plotting tanks were used extensively toplot three-dimensional heat transfer and fluid flow fields. The theory behind these tanksis the well know electrical analogy between electrical fields and temperature or flowfields based on the Laplace equation. These tanks have been essentially replaced withmodern computational methods.As part of a student project, a set of small plotting tanks were designed and built to use asa heat transfer lab on two-dimensional conduction. These particular tanks have beendesigned to simulate a variety of boundary conditions. Readily available saline solutionis used as the electrolyte. In order to simplify the plotting, and to reduce the over cost amodified common pencil is used as the probe, and the plot is made directly on a sheet ofpaper at the bottom of the container. Boundary conditions are simulated using up to 5volts DC.This paper describes the development of these devices and the test results. Results havebeen compared to finite difference plots and to ANSYS plots to verify that the tanks areworking as intended, and these results are included in the paper. The simple tanks yieldresults very close to the analytical methods. Also included in the paper is a brief historyof electrolytic plotting tanks, the relevant theory and a description of a potential labexercise using these tanks.
