In the present work, we conducted a numerical simulation of flow and sediment transport and deposition in a meandering river. The corresponding results were compared to experimental data of a physical river that was assumed to have a 0.001 longitudin

Heat transfer from the laser keyhole to the weld pool and details of the fluid flow play an important role in determining weld shape and size. In this work, both the experiment and the finite volume method (FVM) are utilized to investigate the therma

Gravitactic bioconvective patterns created by Tetrahymena pyriformis in a Hele-Shaw apparatus were realized and compared with theoretical results. There were found to be two thresholds for bioconvection development: the first indicates the transition
