A PC-Based Transient Method for Thermal Conductivity Measurement

In this paper, an indigenously developed thermal probe has been interfaced with a PC for automated measurement of thermal conductivity (K ). The developed system has been calibrated and standardised by measuring K of glycerol. The maximum percentage error, for repeated sets of observations, was within 7.29 per cent of standard value reported for glycerol. This methodology has been successfully employed for measuring K of propellant oxidisers, additives, binders, etc.
