A Blower manufacturer based in North America received some tough feedback from its customers.
Customers wanted the company to design blowers with significant reduction in energy consumption (at least 10% to 15%) as well as the lowering of operating noise levels. And this had to be achieved without compromising the quality of its output.
Without these improvements in their next product variant the company significantly risked losing market share. They decided to follow a CFD-led product design process to achieve these aggressive design goals.
To achieve the goals we did a computational study of the following design parameters:
Based on the CFD simulations:
We then validated these results against experimental data.
The mandate of the project was to predict performance to enable design improvements using CFD which we accomplished.
With performance prediction we recommended the following design improvements:
