Energy balance of a 2-D model for lubricated oil transportation

... The full problem is that of a three-dimensional flow in a cylindrical pipe of two immiscible fluids, water and oil, governed by the transient NavierStokes equations. On entering the pipe, the fluid with low viscosity (water) is adjacent to the pipe wall and it surrounds the fluid with high viscosity ...

... (a) The work required to stretch a spring depends on the square of the amount of stretch. Therefore, to stretch a spring by the amount x requires only 1/4 the work required to stretch it by the amount 2x. In this case, the work required is W0/4. (b) To stretch this spring by 3 cm from equilibrium re ...

Eigenstate thermalization hypothesis

The Eigenstate Thermalization Hypothesis (or ETH) is a set of ideas which purports to explain when and why an isolated quantum mechanical system can be accurately described using equilibrium statistical mechanics. In particular, it is devoted to understanding how systems which are initially prepared in far-from-equilibrium states can evolve in time to a state which appears to be in thermal equilibrium. The phrase ""eigenstate thermalization"" was first coined by Mark Srednicki in 1994, after similar ideas had been introduced by Josh Deutsch in 1991. The principal philosophy underlying the eigenstate thermalization hypothesis is that instead of explaining the ergodicity of a thermodynamic system through the mechanism of dynamical chaos, as is done in classical mechanics, one should instead examine the properties of matrix elements of observable quantities in individual energy eigenstates of the system.
