Category: Transient Plane Source
Author(s): Steven Michael Rhyder Goodhew
Abstract: The transient plane source method is used to measure the thermal conductivity, thermal diffusivity and the specific heat of solid and some liquid materials. With the hot-disk instrument, a double spiral nickel sensor is sandwiched between two homogenous samples, and as the sensor pulses electrical currents through the sample, it simultaneously measures how long it takes for the temperature of the sample to increase. Assessment of cob walling should take place in-situ¬, ¬whereas the transient plane source technique takes place in a laboratory setting, therefore it is not suitable for determining the thermophysical properties of cob walling.
