Rational Technique for Multistage Centrifugal Pump CFD-Modeling

Abstract

This article reports CFD-modeling technique of flow through a kerosene pump and suggests appropriate CFD tools, model configuration, types of boundary conditions, turbulence models and meshing technique. The flow features were analyzed and error of the CFD-model was estimated. The CFD results were compared with experimental results. The final CFD-model, which was also verified with the impeller radial load estimation, shows that the technique produces sufficient accurate results with less computational cost. The technique can be used for the design optimization of a multistage pump.

Centrifugal pumps performance estimation with non-Newtonian fluids: review and critical analysis

“…As turbulence model, standard k-ω is chosen. This model has shown successful applications in the simulation of centrifugal pump as reported, for instance, by Zubanov et al (2015) and Song et al (2003). Figure 2 reports the numerical domains used in the present work.…”

Optimization of Powerful Two-stage Screw Centrifugal Pump

“…The second CFD-model contains the mesh model v0 of blades and mesh models of KID and VOD from rough mesh of previous study [3]. Gas-dynamic optimization of the working process of the powerful fuel pump was performed.…”

“…In this paper, a proven CFD model will be used from the previous study [3]. Water was used as the working fluid because the experimental test data for water were available.…”

“…3) the combination of the first two approaches. Investigation of the working process in previous studies [3,4] showed the presence of vortex zones in the high-performance pumps. The high-performance fuel pump was adopted as the study subject ( Fig.…”

The Technique for CFD-Simulation of Fuel Valve from Pneumatic-Hydraulic System of Liquid-Propellant Rocket Engine

“…However, using of popular in recent years CFD-simulation technologies of hydrodynamic processes of liquid rocket engines [1,2], allows to perform even optimization researches on high-level models (in fact, virtual prototypes), but in the domestic rocket-engines industry it is still not widespread. Therefore, at the present time, young specialists are faced with the task of developing and mastering CFD-simulation technologies, which in the conditions of modern re-equipment of computational tools (the emergence of cluster computing technologies, supercomputers), will provide a fast pace of designing, manufacturing and testing LPRE aggregates [3,4,5]. This work shows clearly modern simulation tools applicable to space rocket industry.…”
