- Abstract
- An electronic instrument is described which permits solution of transient heat-flow problems by use of direct analogy to electrical networks. The instrument is of the so-called "fast-time" type, simulating the transient involved in times of the order of 10-6 that of the thermal prototype. A photoformer type of input-signal generation is used and this, together with a variable-frequency master oscillator, permits flexibility of input-signal waveform and time scale. Some applications of the instrument to the field of fire research are described. The discussion of errors includes consideration of those resulting from the lumping of circuit elements.
