One-dimensional advection. ¶. Solve the linear advection equation: qt + uqx = 0. q t + u q x = 0. Here q is the density of some conserved quantity and u is the velocity. The initial condition is a Gaussian and the boundary conditions are periodic. The final solution is identical to the initial data because the wave has crossed the domain.. Mathematically, we’ll start with our two equations: (1) The diffusion equation without heat production and (2) the advection equation, then combine them. In steady state, we can ignore the transient term ∂T/∂t ∂ T / ∂ t, so. Another way to write the previous equation is. In this case, we can make some substitutions and find something.
