Compressible flow

The main difference between compressible flow and almost incompressible flow is
not the fact that compressibility has to be considered. Rather, the difference is in
two phenomena that do not exist in incompressible flow. The first phenomenon

is the choking of the flow. Choking is [...]

Entropy fix

Let the symbol “a” represent the wave speed. “a” is defined by the derivative
of the flux “f” with respect to the conserved variable “u”, So, for the Burgers
equation, since f = u x u /2, a = u.
At a shock, the characteristics converge and at an expansion, characteristics
diverge. We can use this [...]

Dirichlet boundary conditions

It is otherwise called the periodic boundry conditions.
The idea behind periodic BCs is that whatever goes out comes in. For a domain [-1,1] periodic B.C. simply means that you set u(1,t) = u(0,t) for all t. This means that u(1,t) which comes from the update formula (in your case, say Lax-Fredrich scheme) must be assigned [...]
