A method for determining the transient heat flux across a solid interface, based on experimentally acquired interfacial temperature-time data, is presented. This method results from the application of Duhamel’s integral method to a third order natural splined fit of the discrete data. General case closed form equations that result from splined and least-squares modeling of the experimental data are developed, presented and illustrated.
