简介:
Higher order entropies are kinetic entropy estimators for fluid models. These quantities are quadratic in the velocity and temperature derivatives and have temperature dependent coefficients. We first investigate governing equations for higher order entropies and related a priori estimates for incompressible flows in the situation where viscosity and thermal conductivity depend on temperature according to the kinetic theory. In this situation, we obtain entropic principles for higher order entropies of arbitrary order provided that |Log(T)|_{BMO} + |v/T^{1/2}|_{inty} is small enough. We next discuss the situation of compressible gases. 报告人简介:Prof. Vincent Giovangigli Present position: Research Director of CNRS (French National Center for Scientific Research); Center for Applied Mathematics; Ecole Polytechnique Education: Habilitation in Applied Mathematics; University of Paris 6 Awards: Jacques-Louis Lions prize awards (2011) from the French Academy of Sciences Research interests: mathematical modeling of multicomponent flows Kinetic theory of gases; combustion; scientific computing 欢迎参加!
