Webinar: Onsager’s variational principle, generalized reciprocal theorem, and their applications
The Hong Kong University of Science and Technology
Abstract: In this talk, I will first give a brief review of Onsager’s variational principle (OVP), which is of fundamental importance to linear irreversible thermodynamics. I will then go through Stokes equation and Fick’s diffusion equation to demonstrate its applications. Finally, I will show how the local reciprocal symmetry, which underlies OVP, can be extended to a symmetry at the global scale. If time allows, I will also include the recent application of OVP to the study of coffee-ring effect.
