The three-dimensional inverse design method, where the 3D blade profile is designed for a specified blade loading distribution, has been applied for designing a propeller fan rotor with high efficiency and low noise.
A variety of the blade loading distributions (pressure jump across the blade), vortex pattern (forced vortex, free vortex, and compound vortex) and the stacking conditions (sweep angles) were specified and the corresponding 3D blade configurations were obtained. Among the 22 different designs, 14 propeller fan rotors including the reproduced baseline fan were manufactured by a rapid prototyping based on a selective laser sintering system (SLS) and tested.
The following high-level steps will be shown:
- Performance simulation and review of a complete (i.e. impeller + volute) stage.
- Key choice of design parameters for the impeller and volute design.
- Control and manipulation parameters such as blade loading for the impeller and specified inlet velocity distribution for the volute.
- Performance simulation and review of the optimized design
The presentation will also consider the impact of different manufacturing methods on the final design. This will be followed by a live Q&A with the presenter.
All attendees of the live session will receive an exclusive piece of content.
