The growing demand for high quality and high efficient household appliances has reached the residential kitchen. Among different kitchen household devices, a quiet performance is especially relevant for cooktop extractors, which currently reach high noise levels during operation. The key component of the cooktop extractor affecting the acoustic comfort is the blower fan unit, which represents the dominant noise source.

The current recording, originally presented at the NAFEMS World Congress 2021, emphasizes how Aeroacoustic-Simulation plays a significant role by providing a detailed understanding of the underlying noise generation mechanisms, allowing engineers to make effective modifications in order to achieve acoustic comfort.

Recording Highlights:

• General overview of the Lattice-Boltzmann Method solver PowerFLOW®
• Presentation of unsteady flow and noise analysis results
• Identification of dominant acoustic noise sources with the FIND-Module from PowerFLOW (Flow Induced Noise Detection)
• Display of an optimized blower design, highlighting the potential of PowerFLOW to quickly evaluate a geometry design modification
