The flow in a rectangular channel with sudden contraction and expansion

On the 1D modeling of fluid flowing through a Junction

“…Remark that the modeling of compressible fluid flowing through pipes with sudden enlargements can be achieved through several entirely different techniques, for instance the isothermal lattice-Boltzmann methods, see [1], or the full system of Navier-Stokes equations, see [18], whereas experimental data are also available in the literature, see [10,16,17].…”
