ABSTRACT
In this chapter transient conduction is treated for which the causative heating is periodic and has continued for a long time. Steady-periodic heating is important in reciprocating machinery, in manufacturing processes, and in naturally occurring temperature cycles such as day/night and summer/winter. Steady-periodic heat transfer is also important in thermal property measurements. Generally thermal properties are measured indirectly, with the thermal properties deduced from a systematic comparison between measured temperatures and a thermal model. Thermal modeling is the focus of this chapter; analysis of experimental data (sometimes called parameter estimation) is beyond the scope of this book. For examples of thermal-property measurements involving steady-periodic heating, see for example: Haji-Shiekh et al. (1998); Hu et al. (1999); Naziev (2001); and Wang et al. (2004).
