Detailed Description

Isentropic equation of state for the barotropic Euler equations. The specific internal energy, pressure, and speed of sound are given by:

\begin{align} e &= \frac{k}{\gamma-1}\,\rho^{\gamma - 1}, \qquad p &= k\,\rho^{\gamma}, \qquad a^2 &= \gamma\,k\,\rho^{\gamma - 1}. \end{align}
