Pathways for advective transport

Advective transport in the ocean fundamentally is Lagrangian in nature. At model grid scales, this transport is parameterized by eddy or turbulent exchange coefficients in analogy to molecular diffusion. Nevertheless, much of the transport is by advection on scales larger than the grid cell yet smaller than basin scale. Moreover, flow at these scales tends to be nonstationary in time and irregu...

Analytical Approaches for Solving Neutron Transport Problems

The exact solutions for stationary and non-stationary neutron transport equations corresponding to various source functions are presented. The semi-infinite medium is considered to have a specular-reflecting boundary with angular dependent externally-incident flux. Some adjustments were made to agree the neutron transport theory with astrophysical applications.

Analytical Solutions for Spatially Variable Transport-Dispersion of Non-Conservative Pollutants

Analytical solutions have been obtained for both conservative and non-conservative forms of one-dimensional transport and transport-dispersion equations applicable for pollution as a result of a non-conservative pollutant-disposal in an open channel with linear spatially varying transport velocity and nonlinear spatially varying dispersion coefficient on account of a steady unpolluted lateral i...

Computation of Nonclassical Solutions to Hamilton-Jacobi Problems

This paper is devoted to the construction of numerical methods for the approximation of nonclassical solutions to multidimensional Hamilton-Jacobi equations, for both scalar and vectorial problems. Recent theoretical results have yielded existence of solutions in many cases for which the usual viscosity approach was ill-suited or not applicable. The selection criterion used here is based on a v...

Analytical solutions for sequentially coupled one-dimensional reactive transport problems – Part I: Mathematical derivations

Multi-species reactive transport equations coupled through sorption and sequential first-order reactions are commonly used to model sites contaminated with radioactive wastes, chlorinated solvents and nitrogenous species. Although researchers have been attempting to solve various forms of these reactive transport equations for over 50 years, a general closed-form analytical solution to this pro...
