### Compressible flow using the Noble-Abel Stiffened Gas model

The Noble-Abel Stiffened Gas model
$e\left(p,v\right)=\frac{p+\gamma {p}_{\infty }}{\gamma -1}\left(v-b\right)+q,$ is a simple extension of the perfect gas model to treat compressible flows in dense media, liquid and solids and obtain closed form analytical solutions.

What started as an example in a gas dynamics course taught in Fall 2019, is now a complete description of the gasdynamics in closed form, now published in Physics of Fluids.

Find here your favourite analytical expressions for Riemann variables, expansion and shock jump conditions, isentropes, detonations and deflagrations and the solution to the Riemann problem, as an example.
