Determination of Optimum Outlet Slit Thickness and Outlet Angle for the Bladeless Fan Using the CFD Approach
نویسندگان
چکیده
Bladeless fans are more energy efficient, safer due to the hidden blades, easier clean, and adjustable than conventional fans. This paper investigates influence of airfoil’s outlet slit thickness on discharge ratio by varying an Eppler 473 airfoil from 1.2 mm 2 in intervals 0.2 using a k-omega SST turbulence model with all y+ wall treatment used numerically simulate CFD. The computational results indicated that smaller slits showed higher ratios. 18.78, 24% increase slit. effect angle pressure drop across was also studied. Outlet angles were varied 16° 26° interval 2°. profile 24° maximum difference 965 Pa between leading edge. In contrast, least 355 Pa. Parameters such as average velocity (U), turbulent kinetic energy, standard deviation velocity, magnitude assess performance profiles bladeless fan.
