1. 1. Centrifugal Turbopumps - Flow Physics and Modelling

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Carl Eriksson; Hampus Henåker; [2021]
   Keywords : Centrifugal Pumps; Rocket Science; Turbopumps; Two-Zone Model; Impeller; Vaneless Diffuser; Vaned Diffuser; Technology and Engineering;

   Abstract : Choices made in the early stages of a design process are crucial. They dictate many of the limitations and freedoms the designer has in later stages of the design. Informed decisions are therefore crucial at this stage. READ MORE

3. 2. CFD Analysis of Cold Stage Centrifugal Pump for Cooling of Hot IsostaticPress with Validation Case Study

   University essay from KTH/Mekanik

   Author : Shane Hereford; [2017]
   Keywords : CFD; HIP; Quintus Technologies; Centrifugal pump; pump curve;

   Abstract : Hot isostatic pressing (HIPing) has been a growing material treatment process for performance part manufacturingfor over 50 years. This process of using an inert gas at high temperature and pressure to densifymaterials leads to vastly improved material properties by removing pores and other micro- aws. READ MORE

4. 3. Maintenance optimisation of centrifugal pumps in a European refinery: : A case study

   University essay from KTH/Industriell produktion

   Author : Andrei Laquet; [2015]
   Keywords : ;

   Abstract : Maintenance has gained credit over the past decades. The oil and gas industry requires efficient maintenance programs due to the hazardousness surrounding the industry. Crude oil margins are also dropping and maintenance yields high controllable costs. Therefore, safety and economy are the driving forces of maintenance optimisation. READ MORE

5. 4. Development of pump geometry for engine cooling system

   University essay from KTH/Kraft- och värmeteknologi

   Author : Joel Björkman; [2015]
   Keywords : pump engine cooling pump curve impeller;

   Abstract : The engine cooling system is an important part of the engine’s performance to achieve optimum temperatures in cylinders and provide cooling to subsystems. With increasing emission demands from legislation, further development of the cooling system is necessary. READ MORE

6. 5. Reducing Pumping Related Electricity Costs - A Case Study of Three Water Utility Companies in Zambia : Energy Efficiency in Pumping

   University essay from KTH/Energiteknik

   Author : Bennet Siyingwa; [2013]
   Keywords : Pumping costs; Pump Rehabilitation; Energy Audits; Reducing Electricity Costs; Pumping; Energy Efficiency; Pumping Infrasturcture; Centrifugal Pumps; Induction Motors;

   Abstract : Electric pumps are extensively used in many industrial and commercial applications worldwide and account for about twenty percent of the world’s electrical energy demand. The useful energy consumed by the pumps is less than what they demand due to inefficiency caused by a number of reasons including the mismatch between the rated operating conditions and their actual operating conditions.
