Direct numerical simulation of turbulent heat transfer in concentric annular pipe flows
, 2021The effect of radius ratio on turbulent convective heat transfer within a concentric annular pipe has been studied using direct numerical simulation. Four radius ratios ( R i / R o = 0.1–0.7) have been compared at a fixed Reynolds number, where Ri and Ro

Large-Eddy Simulation of turbulent heat transfer in a multiple-started helically rib-roughened pipe
International Journal of Heat and Mass Transfer, 2020Large-Eddy Simulations (LES) of single-phase turbulent heat transfer in an internal helically ribbed pipe were performed for R e = 8000 and 16000 and Pr = 5 , 7 , 9 . The multiple-started rib-roughened pipe has been designed for heat transfer enhancement

Status and perspectives of turbulent heat transfer modelling in low-Prandtl number fluids
Nuclear Engineering and Design, 2019Thermal-hydraulics is recognized as a key safety challenge in the development of liquid metal cooled reactors. At nominal operating conditions, the Prandtl number of liquid metals which are used as primary coolants, such as lead and sodium, is very low ...
