In the enthalpy-based pressure-correction formulation, the closure evaluates temperature T, density $\\rho$, and compressibility coefficient $\\psi$ from the solver state (h,p,Y) through enthalpy-temperature inversion and repeated real-fluid equation-of-state evaluations. Neural-network surrogates offer fixed-cost inference, but direct mapping from (h,p,Y) to $(T,\\rho,\\psi)$ must capture the enthalpy-temperature relation and non-ideal equation-of-state response, resulting in a comp","authors_text":"Han Li, Haoze Zhang, Ke Xiao, Runze Mao, Yangchen Xu, Zhi X.
