Extensive Review on Blade Profile, Tip Clearance Gap and Vane Casing on Axial Flow Fan

This paper presents a review of the airfoil profile using Bezier curve, tip clearance gap and refining of vane casing treatment (RVCT) of an Axial-flow Fan. In turbomachinery field many important rotating component or element inside the system. To optimize fan performance by reducing energy demand by adjusting rotating components from an aerodynamic standpoint. The fan has a lot of energy-saving potential, but it needs to be enhanced in order to maximize performance and reduce power consumption. The Axial Flow Fan is used in the automotive, aircraft, and electrical and mechanical industries. As a result, the axial flow fan's efficiency is critical. Review of fan applications in engineering from the beginning to the present day, from basic to complex. The axial flow fan's aerodynamic nature, structure, and casing treatment are also critical for its efficient use. Efficient aerofoil profile with appropriate tip gap clearance and RVCT has been well-designed for a variety of layouts varying efficacy from the standpoint of a stabilizing mechanism after a half-century of research. This research focuses on one of the most important design features of mine ventilation fans industries and other industries. With the advancement of CFD and better measuring techniques, the mine ventilation fan combined with acceptable aerofoil profile and appropriate tip clearance gap, RVCT methodology will continue to exist as a broad and economical choice in the future, and the screening for its cogency texture will become more thorough.
