shock tube
How do I find the entropy of flow in a shock tube given P,rho,V?

Regards Shuo

Re: shock tube
entropy=p/rho^gamma in the shock tube problem

Re: shock tube
And is internal energy P/(gamma - 1)+rho*u^(2)

Re: shock tube
I also ploteed the mass flux (rho*V) variation in a shock tube. it's not constant! Shouldn't mass flow be conserved?

Re: shock tube
No. If you considered an ideal gas law, the internal energy is rho*e=p/(gamma-1) in which e stands for the internal energy.

Re: shock tube
Your did stand for the total energy, not the internal energy.
