Heat Transfer Uncertainty (Landrum)
Research Overview

• Objective Evaluate heat transfer correlations
  and uncertainties for supercritical hydrogen
• Scope Effects of cooling channel curvature,
  aspect ratio, roughness, and asymmetric heating
• Significance Prediction of regen cooling system
  performance application to expander cycles

• Approach
• Review of experimental
• analytical data
• Regions of validity mapped
• Hydrogen property survey
• Detailed uncertainty analysis

• Anticipated Results
• Uncertainties in correlations may have
• large impact on performance predictions
