چکیده

Starting from the most general formulation of stochastic thermodynamics—i.e. a thermodynamically consistent nonautonomous stochastic dynamics describing systems in contact with several reservoirs—, we de€ne a procedure to identify the conservative and the minimal set of nonconservative contributions in the entropy production. Œe former is expressed as the di‚erence between changes caused by time-dependent drivings and a generalized potential di‚erence. Œe laŠer is a sum over the minimal set of ƒux–force contributions controlling the dissipative ƒows across the system. When the system is initially prepared at equilibrium (e.g. by turning o‚ drivings and forces), a €nite-time detailed ƒuctuation theorem holds for the di‚erent contributions. Our approach relies on identifying the complete set of conserved quantities and can be viewed as the extension of the theory of generalized Gibbs ensembles to nonequilibrium situations.

Structure of Entropy Solutions for Multi{dimensional Scalar Conservation Laws

An entropy solution u of a multi{dimensional scalar conservation law is not necessarily in BV , even if the conservation law is genuinely nonlinear. We show that u nevertheless has the structure of a BV {function in the sense that the shock location is codimension{one rectiiable. This result highlights the regularizing eeect of genuine non-linearity in a qualitative way; it is based on the loca...

Hyperbolic Systems of Conservation Laws

Conservation laws are first order systems of quasilinear partial differential equations in divergence form; they express the balance laws of continuum physics for media with "elastic" response, in which internal dissipation is neglected. The absence of internal dissipation is manifested in the emergence of solutions with jump discontinuities across manifolds of codimension one, representing, in...

Validity of Nonlinear Geometric Optics for Entropy Solutions of Multidimensional Scalar Conservation Laws

Nonlinear geometric optics with various frequencies for entropy solutions only in L∞ of multidimensional scalar conservation laws is analyzed. A new approach to validate nonlinear geometric optics is developed via entropy dissipation through scaling, compactness, homogenization, and L–stability. New multidimensional features are recognized, especially including nonlinear propagations of oscilla...

Hybrid entropy stable HLL-type Riemann solvers for hyperbolic conservation laws

It is known that HLL-type schemes are more dissipative than schemes based on characteristic decompositions. However, HLL-type methods offer greater flexibility to large systems of hyperbolic conservation laws because the eigenstructure of the flux Jacobian is not needed. We demonstrate in the present work that several HLL-type Riemann solvers are provably entropy stable. Further, we provide con...

Waves in Systems of Conservation Laws: Large vs Small Scales

Several results about the stability of waves in systems of conservation/balance laws, disseminated in the litterature, obey to a common rule. The linear/spectral stability of the microscopic pattern (the internal structure of the wave) implies the well-posedness of a macroscopic Cauchy problem for an other system of conservation laws. The latter is often obtained by retaining only the conservat...

Entropy Stable Approximations of Nonlinear Conservation Laws

A central problem in computational fluid dynamics is the development of the numerical approximations for nonlinear hyperbolic conservation laws and related time-dependent problems governed by additional dissipative and dispersive forcing terms. Entropy stability serves as an essential guideline in the design of new computationally reliable numerical schemes. My dissertation research involves a ...
