Solve advection equation
The advection equation is the partial differential equation that governs the motion of a conserved scalar field as it is advected by a known velocity vector field. It is derived using the scalar field's conservation law, together with Gauss's theorem, and taking the infinitesimal limit. One easily visualized example of advection is the transport of ink dumped into a river. As the river flows, ink will move downstream in a "pulse" via advection, as the water's movement itself transp… WebMar 1, 2024 · , An analytic solution for the space–time fractional advection–dispersion equation using the optimal homotopy asymptotic method, Comput.
