Dear researchers,
It's easy to solve the heat conduction problem in 1D composite media (e.g., multilayered cylinder) as shown in chapter 10 of the book 'Heat conduction 3rd 2012, Hahn & Özişik' by using the Quasi-Orthogonal Functions proposed by Tittle 1965.
However, which orthogonal expansion techniques can be used to solve the problem in multidimensional composite media (e.g., orthotropic multilayered cylinder)?
Can I have some relevant materials for solving my question, please?
Thank you all so much.
Kind regards,
Sam.
