This project was initialized as a response to industry demand for an improved impeller for gas dispersion. Several impeller prototypes were built and tested in 0.61 m diameter test rig, CFD and PIV. Analysis was focused on different combinations of blade shape, blade size, and blade location in relation to axis of rotation. All impeller prototypes were made by Laser Stereo Lithography method to ensure accuracy of shape. The project resulted in an optimized design that provides excellent process results, can be built for high power applications, and can be assembled on site.
