Industrial Air Purifiers: CFD Investigation for Optimized Duct Design for Noise Reduction and Performance Enhancement

Abstract

Abstract This research investigates into the critical intersection of fluid dynamics and noise generation within industrial air purifier ducts. As industrialization escalates, so does the concern for environmental challenges and air pollution. Industrial air purifiers, designed to combat airborne contaminants, play a pivotal role in fostering cleaner and healthier industrial environments. However, the accompanying noise from essential components poses challenges for worker well-being and operational efficiency. Utilizing Computational Fluid Dynamics (CFD) simulations, our investigation systematically explores the impact of duct geometry on fluid dynamics, turbulence, and noise generation. Validation against experimental data ensures the accuracy of our numerical model. The deliberate variations in duct design across five models, coupled with subsequent simulations for four additional designs, reveal Design 5 as a successful contender in achieving noise reduction objectives. Comparative analyses of outlet velocities, inlet pressures, and sound levels provide actionable insights for engineers and manufacturers. This research not only advances our understanding of duct geometry’s role in noise generation but also paves the way for quieter and more efficient industrial air purifiers. The optimized designs contribute to creating industrial environments that prioritize both workplace well-being and environmental sustainability.
