Software for Probabilistic Thermal and Structural Analysis

NESTEM is a computer code that is a combination of a heat-transfer-analysis subprogram and a NASA in-house probabilistic-analysis code called "NESSUS" (for Numerical Evaluation of StochasticStructures Under Stress). NESTEM can be used to analyze a complex combustor thermal environment with uncertainties and to assess the effects of the environment and the uncertainties on the overall responses of components. NESTEM is expected to help in the development of a comprehensive probabilistic methodology for reliable and robust design of such major turbine-engine components as compressors, turbines, impellers, and combustors.
