Validation Exercises

The “Validation Methods” developed in the PECOS Center are applied to the models used in the simulation vehicle entry into the atmosphere. Validation is applied to the simplest component models and to various combinations of models used to represent multi-physics phenomena, and finally to the integrated full system model. Critical to the validation process is reliable experimental data for test scenarios that challenge the models. In the PECOS center, these validation exercises serve to both build confidence in the models and to test the validation methods. The planned validation exercises include validation of:

• Chemistry and radiation models using shock-tube data
• Turbulence models using published data and data from new experiments at UT
• Ablation models using data from new experiments at UT
• Coupled turbulence and chemistry/radiation models
• Coupled turbulence and ablation models
• Coupled full system models used for prediction
