查询词典 turbulent

The simulation results show that the rod baffles placed vertically and horizontally in the unit duct continuously shear and comminute the streamlines of the flow when the fluid crosses over the rod-baffles, change the fluid flow directions, and result in the disruption of the continuity and stability of the fluid. The disturbing flow can promote the fluid turbulent intensity and effectively enhance the heat transfer.
