Abstract
Described in this paper is analog simulation techniques for analysis of heat-conduction problems. Here is given a principle of analog simulation of heat-conduction by a lumped-parameter electric RC network, together with an illustration of the device. Also shown is an example of the analysis of steel ingot solidification by two dimension electric analog simulator. Accuracies of one and two dimension electric analog simulators are considered in detail. A new technique is introduced for simulation of variabl-parameter thermal systems by a simple constant-parameter RC network. The electric analog simulator has an accuracy good enough for practical use. Its operation speed is very high, usually about 50 times as fast as middle-class digital computers, Furthermore, the programming and handling of the electric analog simulator are quite simple.
