Simulation-Based Noise Estimation for Cooling Fan Designs
Regal Rexnord needed to develop a simulation-based method of estimating noise levels for their electric motors due to changes in cooling fan design. Previously, physical testing was used to predict the noise levels. As part of a new development platform, they decided to use a simulation-based noise prediction method at the preliminary design stage. In order to accelerate the development of the simulation-based noise method, Regal Rexnord engaged with ANSYS Mentor Expert Services that provided explicit training on developing a methodology for aeroacoustics simulation.
Challenges
Using Fluent® software from Ansys for aeroacoustics simulation, had challenges in developing a simulation model in predicting the noise. Hence, Marathon Electric India Pvt. Ltd, decided to seek expert mentoring from ANSYS, which helped them to quickly solve existing problem and develop a methodology for future cases.
Technology Used
The ANSYS Mentor Expert Services was used for aeroacoustics simulation using Fluent software from Ansys.
Engineering Solution
- CFD simulation techniques were used to predict noise for the new fan design for a new high-efficiency motor
- Advice from ANSYS Mentor Expert Services provided insight into noise prediction, the sources of noise generation and ways to reduce the noise levels
Benefits
- ANSYS Mentor Expert Services helped Marathon Electric India Pvt. Ltd. in predicting fan noise at a preliminary design stage.
- The ANSYS Mentor Expert Services helped the team to develop an aeroacoustics simulation methodology in Fluent® software from Ansys and gain in-house expertise for doing future simulations in acoustic domain.
