Unified Form EOS for Detonation Products based on relationship between initial density and detonation velocity

We have proposed the unified form EOS for detonation products, which employs Gruneisen $\Gamma $ as a specific volume in previous paper. When the relationship between the initial density and detonation velocity, and one C-J state and P-V isentrope line passing through the corresponding C-J point are known, the proposed method can be used to obtain Gruneisen $\Gamma $. In the report, the unified form EOSs are applied for SDT problems for PETN, and so on.
