“…While studying the performance of a small industrial fan Quinlan and Bent [21] were able to demonstrate that blade tip anti-vortex appendages were an effective passive noise control technology [20,[22][23][24]. Akturk and Camci [25] reported on a novel tip platform extension experimental study the resulted in more efficient fan with improved acoustic performance as a consequence of the control of flow swirl.…”

“…The tip end-plate technique is based on modifications to the blade tip by means of antivortex appendages. Quinlan and Bent [44] have proposed end-plates, and others have proposed various solutions in patents for industrial fans [45^8]. Corsini and Sheard [49] proposed the use of a three-dimensional end plate to promote simultaneously tip flow control and a turbulence screen etihancer.…”

This review aims to assist engineers in understanding and applying passive solutions for reducing industrial fan noise. The paper systematically reviews the extant literature on passive noise techniques, with a particular focus on experimental rather than theoretical research. The review provides an assessment of the current state of the art in industrial fan flow and noise control. It offers a vision for potential improvements in noise reduction via novel application of flow and noise control technologies. The review examines the interaction between aerodynamic cause and acoustic effect and the application of control technologies that current cause and effect theories have inspired. The purpose is to provide a vision for aerodynamics research during the next decade that will serve as a basis for systematically reducing industrial fan noise emissions. The review provides an assessment of recent flow and noise control advances and considers some opportunities for future research. The review reflects an emphasis on low-speed industrial fans. The authors consider high-speed turbomachinery noise control, with the objective of illustrating the linkages between the two technologies. The review concludes with a summary of the opportunities for future research and its application to flow and noise control in industrial fan design.

“…For the outdoor set without an air outlet louver the total sound pressure level is 55.7 dB. There are some researches on controlling of the aerodynamic noise generated by the axial fan [7][8][9][10]. But the influence of the air outlet louver is not included.…”
