Application

• Turbulent Combustion by Dr. Jackie Chen at SNL, and Dr. John Bell at LBNL

Goal: understanding turbulent combustion

• Combustion provides 85% of the US energy needs
• Low emission/temperature engines will operate at combustion regimes currently poorly understood
• Need new understanding of turbulence-chemistry to predict efficiency and pollutant emissions

Requirement: exploration of flexible Feature definition, analysis and tracking

• Develop robust feature definition
• Allow user to change parameters interactively and evaluate consequences on results
• Track features over time based on variable correspondence parameters
• Concurrent analysis of multiple fields restricted to the features of interest

Challenges

• Accurate combustions simulation generate massive datasets that are hard to manage in postprocessing
• The data needs to be inspected by the user since selection parameters are not predetermined
• For each parameter selection
  • the user needs to get access the shape characterizations
  • understand the consequence on events like merging or splitting of features of time
