Numerical Integrators for Dispersion-Managed KdV Equation

Communications in Computational Physics, 2022
In this paper, we consider the numerics of the dispersion-managed Korteweg-de Vries (DM-KdV) equation for describing wave propagations in inhomogeneous media. The DM-KdV equation contains a variable dispersion map with discontinuity, which makes the solution non-smooth in time.

Numerical modelling of birch pollen dispersion in Canada

Environmental Research, 2021
Simulating allergenic tree pollen is important to protect sensitive population and to support bioaerosols monitoring effort. Using the regional air quality model GEM-MACH, a simulation was conducted adopting two new main hypotheses: 1) the use of vertical correlation concept to force the vertical dispersion (a method normally used in tracer data ...

Multidimensional Numerical Dispersion

Society of Petroleum Engineers Journal, 1983
Abstract Numerical dispersion can cause a smearing of otherwise sharp saturation fronts. The usual methods of estimating the magnitude of the smearing effect in one dimension (1D) are shown to apply in two and three dimensions (2-and 3D) as well.

Numerical Solution to a Dispersion Equation

Journal of the Hydraulics Division, 1964
A semi-implicit numerical solution to the differential equation of dispersion in a two-dimensional open channel is developed. Some of the details of the iterative technique and the computer solution are shown. The results for turbulent flows show that the longitudinal distribution of solute concentration approaches a Gaussian (normal) pattern as the ...

Numerical Dispersion of Gravity Waves

Monthly Weather Review, 2009
Abstract When atmospheric gravity waves are simulated in numerical models, they are not only dispersive for physical but also for numerical reasons. Their wave properties (e.g., damping or propagation speed and direction) can depend on grid spacing as well as on the numerical schemes.

Numerical dispersion and absorbing boundary conditions

International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 2000
Summary: Predictions of performance of exact and approximate absorbing boundary conditions (ABCs) do not take into account the fact that in an actual simulation it is numerical waves that are incident on the computational domain boundary where they are imposed. Via a model problem in rectangular co-ordinates we identify and examine this issue. Then, we
