Heat transfer to liquid metals in longitudinally wetted bundles of rods

Sodium-heated steam generator model tests at SGTR. Volume 2. Thermal- hydraulic performance data and analysis.

“…The sodium temperature in the calming region {Figure 4-10) near the sodium level is lower than the sodium inlet temperature as shown in Figure 6-1 and measured by thermocouples 13 and 14 {Figure [4][5][6][7][8][9][10][11][12][13][14]. Although insufficient data are available to show what the sodium temperature profile was like in this region, the measured temperatures are given in Table B-7, along with other thermocouple data.…”

HLM fuel pin bundle experiments in the CIRCE pool facility

“…Mikityuk correlation is here reported: Nu = 0.047 · (1 − e −3.8·(x−1) )(Pe 0.77 + 250) valid for 1.1 ≤ p/d ≤ 1.95 and for 30 ≤ Pe ≤ 5000 (6) It gives the best fit of four sets of experimental data (658 data points). It is obtained from the review of experimental results obtained by Mareska and Dwyer (1964), Borishanski et al (1969), Gräber and Rieger (1972) and Zhukov et al (2002) and triangular lattice of rods with p/d ratio of 1.1-1.95 and Peclet numbers up to 5000, it must be stressed, however, that correlations have an uncertainty due to the heterogeneity of the original data and moreover they are derived for different heavy metals.…”

An Efficient Scheme for Coupling OpenMC and FLUENT with Adaptive Load Balancing

“…With this model, the CFD code is enabled to generate overlapped solid regions in the porous regions, so that the temperatures of solid and liquid can be obtained, respectively, which will be transmitted to the MC program for further computing. e heat transfer coefficient of solid material can be set based on the formula proposed by Borishanski et al [43,44].…”
