On the Preliminary Design and Performance Prediction of Centrifugal Turbopumps—Part 1A reduced-order model for the preliminary design and performance prediction of radial turbopumps is illustrated. The model expresses the 3D, incompressible, inviscid, irrotational flow through helical blades with slow ...

The present research effort deals with simplified theoretical models for the preliminary design and performances assessment of centrifugal pumps for liquid rocket propulsion. These models have been developed within the Concurrent Design Facility, under development at the Italian Aerospace Research Centre (...
Sizing centrifugal pumps Normal flowrate and rated flow-rate. To define the normal and rated flowrates, refer to the heat and mass balance of your project. Normal flow-rate is the flow at 100% capacity. Rated flowrate is the design margin that is added ...

Two centrifugal pumps in series were used to supply adequate operating pressure to the TRC system in the supercritical state of the working fluid. The operating pressures were controlled using the variable frequency drive (VFD) of the second pump. The efficiency of the expander and working fluid ...
Efficient selection of centrifugal pumpsBLADE INLET ANGLEPERFORMANCE IMPROVEMENTIMPELLERTURBINENUMBERPumping systems are among the most energy-consuming applications, making its efficient operation a matter of great relevance. In recent years, efforts to improve the efficiency of these systems have followed ...
