 March 16, 2008, 16:55 Solid EOS #1 adam Guest   Posts: n/a Hi I need EOS for a Solid phase. Can some one introduce an EOS in the form: P = ????? i.e. an EOS similar to the ideal gas. Am modeling a mixture of gas-solid two-phase flow, 1-D. Thank you for your help and guidance.

 March 17, 2008, 18:47 Re: Solid EOS #3 jinwon park Guest   Posts: n/a Or you can also see the Gruneisen EOS. The stiffened gas EOS is a reduced form of the Gruneisen EOS.

 March 18, 2008, 04:57 Re: Solid EOS #4 adam Guest   Posts: n/a i have looked to Gruneisen EOS but i couldn't derive a formula for: P = ......... can we use the ideal gas EOS for a solid? i.e. P = k \rho^{gamma -1} Thanks

 March 18, 2008, 09:06 Re: Solid EOS #5 jinwon park Guest   Posts: n/a The stiffened gas EOS is able to be recast as it.

 March 18, 2008, 15:12 Re: Solid EOS #6 adam Guest   Posts: n/a Many thanks for your reply. I hope you, or any one out there, will help me about the following. The EOS is: e_{k} = \frac{P_{k} + \gamma_{k} P_{0}}{\rho_{k} (\gamma_{k} - 1)} where k = g (gas), s (solid) * For the GAS phase I have taken: P_{g} = K_{g} \rho_{g}^{(\gamma_{g} - 1)} with P_{0} = 0 ** what shall I use for the solid phase. P_{s} = what............. ? Am doing mathematical analysis for a compressible mixture of gas-solid two-phase flow in 1-D only.
