Investigations of single-phase flow mixing characteristics in a wire-wrapped 37-pin bundle for a sodium-cooled fast reactor

Applicability of RANS models and pressure drop in edge subchannels for 19-pin wire-wrapped fuel bundle channel in CiADS

“…The experimental data allowed for the determination of the average velocity, root-mean-square (RMS) fluctuating velocity and the Reynolds stress of the flow field. Numerical research: Kim et al [ 19 ] used STAR-CCM + to calculate the flow characteristics in a 37-pin fuel assembly featuring a pin-to-rod diameter ratio of 1.13, with deionized water utilized as the working fluid. The results derived from the k-ε model displayed excellent concurrence with experimental data.…”
