An Equilibrium Ablation Boundary Condition for the Data-Parallel Line-Relaxation Code

摘要

A Gibbs free-energy minimization solver has been developed to compute the equilibrium saturated mixture composition and blowing rate for complex gas/thermal protection system combinations where the surface acts as a source of multiple constituents. This tool has been embedded in the Data-Parallel Line-Relaxation computational fluid dynamics code to perform simulations with equilibrium ablation in a tightly-coupled manner. Such an implementation eliminates the need for blowing corrections for material response analysis.
