Joung, Youghoon, Auteur ; Choi, Sung-Uk, Auteur ; Choi, Jung-II ; Robert J. Martinuzzi, Éditeur scientifique |A direct numerical simulation of turbulent flow in a square duct was performed for a Reynolds number based on bulk streamwise velocity and duct height equal to 4,440. The mechanism by which secondary flows are generated in a square duct was inve[...]

Wonjun Yang, Auteur ; Choi, Sung-Uk, Auteur |This study presents the results of laboratory experiments on depth-limited open channel flow with submerged vegetation. To investigate the impact of stem flexibility on the mean flow and turbulence structures, two flow types with similar drags b[...]

Choi, Sung-Uk, Auteur ; Kang, Hyeongsik, Auteur |A Reynolds stress model for the numerical simulation of partly-vegetated flows is presented. The model uses Speziale, Sarkar, and Gatski’s model for the pressure–strain correlation, Mellor and Herring’s model and Rotta’s model for the diffusion [...]

Choi, Sung-Uk, Auteur ; Park, Moonhyeong, Auteur ; Kang, Hyeongsik, Auteur |The flow and transport of suspended sediment in open-channel flows over smooth-rough bed strips were simulated numerically. The flow equations were solved with the aid of the Reynolds stress model. Simulated flow structures are provided and comp[...]

Kang, Hyeongsik, Auteur ; Choi, Sung-Uk, Auteur |Numerical experiments involving various algebraic scalar flux models for solute transport in open channel flows are presented. Five algebraic scalar flux models including these of Daly and Harlow, Abe and Suga, Suga and Abe, Sommer and So, and W[...]
