Title & Authors
Optimum design and performance of marine sea water pump with impeller using CFRP Jeong, Seon Yong; Rhi, Seok Ho; Seo, Hyoung Seock; Lee, Kye Bock;
Marine sea water pump with impeller using carbon fiber block was developed to prevent the impeller corrosion by the salinity. A numerical analysis was carried out in order to optimize the impeller and volute design for marine sea water pump and to investigate the sensitivity of the related parameters(impeller thickness, surface roughness) using CFD commercial code. The impeller thickness is limited because of the weight. Since the impeller using the carbon fiber lights, the thickness which has a maximum efficiency can be used. The results show that the surface roughness leads to an 7% reduction in pump efficiency.
