Abstract: A novel model equation of state (EOS) for hydrocode is suggested. This model is called the Δχ -EOS because it depends on two functions of one variable each. The Δχ -EOS generalizes the classical incomplete EOS like the ideal gas thermal EOS, the van der Waals EOS, and the virial EOS, among others. We demonstrate the incomplete and complete variants of the Δχ -EOS. We also discuss how to recover the functions Δ?and χ from experimental measurements.
