Multiple co-axial heave plates of uniform geometry are attached to offshore platforms for inducing damping and added mass. These effects generally decrease the magnitude of the dynamic response of the platform under applied environmental excitation forces. When spacing between heave plates is decreased the damping and added mass performance are altered due to their strong vortex interaction. A new non-uniform plate configuration is proposed that may create different hydrodynamic characteristics. The modes of vortex shedding around plate edges in a non-uniform arrangement under forced harmonic oscillation are investigated via the CFD method. Furthermore, a new simplified formula for the total theoretical added mass of a general non-uniform double disk is proposed when it is in the zone which vortex interaction take places. The results show that a non-uniform double disk has better hydrodynamic performance as compared to the uniform double configuration for a given spacing. It is also observed that the mode and direction of the vortex shedding are different for uniform and non-uniform arrangements in a given spacing and KC value.

“…The simulation results are in good agreement with the experimental results. Therefore, the performance curve of the fan can be predicted with reasonable accuracy without requiring a large amount of manufacturing and testing costs [15]. Reference 16 introduces an innovative aerodynamic design scheme of axial flow fan based on constant diffusion factor and radial balance.…”

Based on the CFD simulation of the axial flow fan for air conditioning, a flexible and fast deformation model of axial flow fan is established in this paper. The influence of different fan design parameters on the performance of axial flow fan under different working conditions, such as different speed, air volume and pressure, is studied. A set of intelligent optimization platform for axial flow fan is formed and the performance of a certain type of fan is optimized under the working condition of 22000m3/h flow rate.
