초록

In this study, numerical analysis is conducted to understand the flow characteristics of the radial impeller with the design parameters such as the blade shape and position using the ANSYS Fluent software. The shape of blade is divided into two types, a backward curved blade and an airfoil forward curved blade. To examine the fundamental flow characteristics near the blades, a rectangular flow field is modeled and analyzed. On the other hand, for the impeller rotation analysis, the simulation is performed by modeling the rotational region separately. As a result, the airfoil forward curved blade shows higher outlet flow rate than the backward curved blade. In addition, as the depth of the impeller and the attachment angle of blade increase, the higher flow rate appears.
