Abstract
A novel procedure has been modelled and implemented with the aim to enable precise calculations of the off-design flow field in an axial fan accounting for the existence of curved meridional streamlines. This is achieved by combining off-design radial equilibrium calculations, the streamline curvature method and the surface vorticity method. The written program is used to calculate the head curves and velocity components of a reference fan for a specified range of operating points. Results of the implementation are validated by comparison with CFD simulations and found to be in good agreement.
