Anwendungsbeispiele für Analogrechner: Beispiel 4 — Erwärmung eines Kabels (Wärmeleitung)
Example 4 in Telefunken's 'Application Examples for Analog Computers' series, dated 15 October 1963. It demonstrates how to simulate radial heat conduction in cylindrical cable insulation on an analog computer: the partial differential equation is reduced to a system of eight coupled ordinary differential equations via finite differences (five radial steps), normalized, mapped to a chain of potentiometer-fed integrators, and solved. Results are presented as time-domain temperature curves at each radial node and as spatial temperature profiles at fixed times.
