Modern continuum thermodynamics is a field theory devised to handle a large class of processes that typically are neither spatially homogeneous nor sequences of equilibrium states. The course will address the continuum theory of heat conduction, in which the constitutive laws furnish a mathematical characterization of the macroscopic manifestations of those fluctuations in position and velocity of the microscopic matter constituents that statistical thermodynamics considers collectively. In addition to a nonstandard exposition of the conceptual steps leading to the classical heat equation, the crucial assumption that energy and entropy inflows should be proportional is discussed and a hyperbolic version of that prototypical parabolic PDE is presented. Thermomechanics will come next, a slightly more complex paradigmatic example of a field theory where microscopic and macroscopic manifestations of motion become intertwined. Finally, a virtual power format for thermomechanics will be proposed, whose formulation requires that temperature is regarded formally as the time derivative of thermal displacement. It will be shown that this format permits an alternative formulation of the theory of heat conduction, and a physical interpretation of the notion of thermal displacement will be given.

The course will be taught by Paolo Podio-Guidugli and will be based on his recent book Continuum Thermodynamics (Springer Nature, 2019).
