About JWL Parameters for Verification Case"KingeryBulmash" #60

Closed lattice-naraoka closed 2 years ago

lattice-naraoka commented 2 years ago

Hello! I'm trying to run validation case"KingeryBulmash". (validation/blastFoam/KingeryBulmash/KingeryBulmash_wedge)

JWL parameters of TNT in the validation"KingeryBulmash" seems to be different from the commonly used value. (rho0,A,B,R1,R2,omega,vDet)

What is the value referenced from?

jheylmun commented 2 years ago

Hello, The JWL parameters were selected based on their comparison with the Kingery-Bulmash equations. They are not currently available in open literature, but were provided by a user/collaborator. Any set of JWL coefficients for TNT should produce reasonable results though.

Thanks, Jeff
