It allows for an accurate and efficient treatment ...
The diffusion of perturbations is investigated, beginning with Onsager-type equations for particle current and energy flow and conservation equations. This method takes into consideration the interplay of density and temperature, and the phenomena produced by this interplay—often neglected with other appro...
A numerical approach is proposed to examine the singularly perturbed time dependent convection-diffusion equation in one space dimension on a rectangular domain. The solution of considered problem exhibits a boundary layer on the right side of the domain. We semidiscretize the continuous problem by ...
The formalism required to treat the time‐dependent diffusion of the light particles of a Lorentzian fluid from a given initial state is developed at the microscopic level in terms of an appropriate solution of the Boltzmann equation. Comparison is made with the results obtained from the alternative...
diffusion type, optimal approximation properties are not satisfied by the Galerkin finite 1 2 element method; however, the advantages of geometrical flexibility, higher order accuracy and stability of the finite element method encourage the use of finite el ement methods in such systems of equations....

This book describes numerical methods for partial differential equations (PDEs) coupling advection, diffusion and reaction terms, encompassing methods for hyperbolic, parabolic and stiff and nonstiff ordinary differential equations (ODEs). The emphasis lies on time-dependent transport-chemistry problems, des...
