After changing fundamental models of deterministic systems to stochastic models, SwRI scientists simulate the influence of contaminants in a system.

During component and system development, performance predictions are often based on specific physical characteristics and deterministic operating parameters. System contaminants often modify operating performance, resulting in a change of deterministic equations to stochastic models involving time-varying, probabilistic random variables.

Using contamination sensitivity analysis, testing, modeling, and simulation methodologies, Southwest Research Institute (SwRI) engineers help manufacturers:

  • Design components to function:
    • at given contamination levels
    • for suitable periods of time
    • with acceptable performance
  • Identify contaminant-sensitive components
  • Develop realistic service-life estimates
  • Achieve targeted service life for final designs
