Simulation of heat flow from a line source in support of development of a thermal probe

The use of a thermal probe allows a range of in-situ conditions to be taken into account that impact upon the properties of building materials (λ, α) as encountered in reality. In this study, the transient thermal simulation of a model representing a line source in an infinite material sample has been used to guide the development of an experimental thermal probe apparatus. Simulation produced a series of datasets that have been used to test the data analysis routines used with the experimental probe.
