Numerical study of different Pr number medium turbulent cross flow in staggered tube bundle

The impact of tube bundle layout on the thermal and fluidic behaviour of liquid lead–bismuth eutectic in a helical-coiled once-through steam generator

“…The Peclet number (Pe) of the tube bundle is defined as [ 18 ]: where the specific heat (J/kg.k) is represented by , and the thermal conductivity (W/m.K) is depicted by k.…”

“…From the numerical results, a correlation for Nu is derived. Jiang et al [ 18 ] compared the thermal behaviour of water and mercury over staggered tube banks using the k −ω SST model combined with the Kays turbulent Pr model. They concluded that for mercury flow, molecular thermal diffusion is the largest contributor to heat transfer even in turbulent regimes, and the turbulent intensity is lower in the initial rows of the tube bundle than the later ones.…”
