A review of experimental data and heat transfer correlations for parallel flow of alkali liquid metals and lead-bismuth eutectic in bundles

For the entire ranges of P/D and Pe values in the experiments, this correlation is in good agreement, within ±15%, with the compiled Nu data. The compiled Nu database for LBE flows in bundles of bare heated tubes with grid spacers, has 205 values for P/D = 1.33-1.80 and Pe = 211-3049. The present Nu correlation for alkali liquid metals agrees with the LBE data to within ±20%. This agreement suggests that the proposed Nu correlation for alkali liquid metals in bundles of bare tubes may also be used to calculate Nu for LBE.
