SUMMARY
The discussion centers on the methods used to solve the unsteady state heat transfer equation, specifically the preference for separation of variables over Fourier transformations in heat transfer literature. It is established that the choice of method depends on the domain: Fourier transforms are suitable for infinite domains, while separation of variables is preferred for finite domains with specific initial and boundary conditions. The conversation highlights that both methods are fundamentally similar, as they can lead to the same solutions under different circumstances. A reference to a textbook that utilizes Fourier transforms for solving the heat equation is also provided.
