SURFACE ROUGHNESS INFLUENCE ON THE HYDRAULIC PERFORMANCE OF AN API 610 BB3 MULTISTAGE CENTRIFUGAL PUMP: AN EXPERIMENTAL–CFD STUDY
Surface roughness affects the hydraulic performance and energy efficiency of API 610 BB3 (between-bearings, axially split, multistage) pumps used in oil, gas, and petrochemical service. We quantify its impact using experiments and computational fluid dynamics (CFD). A four-stage pump was tested at 2900 rpm on a closed-...
