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… WebLinear Advection Equation: Since the advection speed a is a parameter of the equation, Δx is fixed from the grid, this is a constraint on the time step: Δt cannot be arbitrarily large.
