explosion parameters
« on: August 29, 2005, 03:49:30 AM »
Hello,

I am working on explosions containment.

In order to model it with the JWL (Jones-Wilkins-Lee) equation of state, I need the JWL  parameters for hydrogen.

Does someone knows these parameters?

Or where can I find these parameters?

Thank you

You must have a supercomputer lying around..

And although you use a so called equation of state... there's enough non equilibrium forces around for me say that its more of a mechanics/engineering problem you have on your hands.

JWL is for condensed (high density) explosives.
 You probably have low-density hydrogen-air
mixture, needing only ideal gas equation.

 To make JWL into ideal gas, set A=B=0,
omega = gamma-1.   rho(0), D, etc depend on
your specific mixture.
          Good Luck.
