영어 초록
The diffuser is effective in closed systems, however, its effect is weaken in open or free flow situations. This can be solved by modifying the rear-end of the diffuser in a manner that enables the formation of strong vortex. By doing that, a large portion of fluid's energy is converted to vortex's dynamic energy, which results in the deduction of static component, or in other words, the decrease of pressure. This study involved the design of rear-end part for efficient hydrodynamic performance of shroud diffusers, and demonstrated with numerical simulation by computational fluid dynamics (CFD). This study focuses on the use of brim end for the shroud where the effect of brim's length and attaching angle are analyzed.
