Measurement of Linear Burn Rates of Heat Producing Systems.

Abstract

A photocell apparatus has been designed to measure the linear burn rate of heat producing systems. The device consists of an electrical unit and a precision viewing unit containing two photocells. A bar shaped sample is ignited at one end, and as the reaction proceeds down the bar, it is sensed by the photocells. The resulting decreases in resistance at the photocells are recorded as two essentially parallel lines. The distance between the two lines is used to calculate the linear burn rate. The device provides a simple method for obtaining reasonably precise linear burn rates.
