Propagating of shock waves in an ideal gas
I am studying gas dynamics and I want to numerically calculate the propagation of a shock wave in an ideal gas.
The problem statement is something like this:
The ideal gas is located in the region $-\...

Can a Mach number be defined for a hot gas fluid element using its own temperature and velocity?
I know that the ratio of an object's speed to the local sound speed is called the Mach number:
$$M = \frac{v}{c_s}$$
where
$$c_s = \sqrt{\frac{\gamma kT}{\mu m_p}}$$
I have always thought of the Mach ...
