We present an explicit fourth-order compact finite difference scheme for approximating the three-dimensional (3D) convection–diffusion equation with variable coefficients. This 19-point formula is defined on a uniform cubic grid. Fourier smoothing analysis is performed to show that the smoothing factor...
The standard wave equation u_{tt}=c^{2}u_{xx} has solutions that propagate with speed c forever, without changing shape, while the diffusion equation converges to a stationary solution \bar{u}(x) as t\rightarrow\infty. In this limit, u_{t}=0, and \bar{u} is governed by \bar{u...
PROBLEM TO BE SOLVED: To obtain equation solution on diffusion which can be executed in a short calculation time as a whole and easily develops a program by reconsidering (v), etc., in the next point from quantity (v) depending on the time and space in a prescribed point to repeat it ...
Based on the concept of Eulerian–Lagrangian method (ELM), the formulation of ELBEM and its associated fundamental solution is obtained for the advection–diffusion equation. Combining ELM and BEM makes it easier to handle the variable velocity field. The ELBEM model performs well for both ...
The inverse source problem for time-fractional diffusion equation: stability analysis and regularization In the present paper, we consider an inverse source problem for a fractional diffusion equation. This problem is ill-posed, i.e. the solution (if it exists... F Yang,CL Fu,XX Li - 《Inve...
