Heat transfer to liquid metal data and correlations for tube bundles

HEAT TRANSFER TO LIQUID METAL:DATA AND CORRELATIONS FOR TUBE BUNDLES

Konstantin MIKITYUK

Laboratory for Reactor Physics and Systems Behaviour


Outline
Outline

  • Liquid metal / tube bundle data review

  • Liquid metal / tube bundle correlation review

  • Analysis of correlation quality for predicting the data

  • Application of the correlations to ELSY conditions

  • Recommendation and conclusion










Analysis of quality of correlations

Absolute error for each data point

Mean absolute error

Standard deviation

Root-mean-square error




Conclusions
Conclusions

  • Only tube bundle data considered

  • No “dirty” fluid data considered:

  • Influence of oxide layer  direct simulation

  • Not enough data to see  / difference

  • Gräber correlation recommended
