Abstract

Axial flow fan occupies an important role in many industrial applications. In this paper, the computational fluid dynamics (CFD) modeling of the axial flow fan of the 7500 kW air-cooled motor is presented. The numerical simulations are performed to analyze the effect of installation angle, pressure variations and the number of blades on the performance of axial flow fan using ANSYS Fluent 16.0. Based on finite volume method, three-dimensional turbulent flow equations are numerically solved. The results show that the volumetric flow rate and efficiency of the axial flow fan are higher when the installation angle is 30° and blades of the fan are 19. Furthermore, volumetric flow rate decreases with the increase in outlet pressure and vice versa. This paper could provide an insightful understanding for the design optimization of axial flow fan and be helpful in designing a fan to improve the overall cooling performance of the systems.
