All rights reserved Effective simulations to ensure optimal performance and correctly predict the hydraulic and thermomechanical behaviour of today’s huge boiler feed water pumps are a challenge for engineers and constructors. Generally, boiler feed water pumps are subjected to extreme mechanical and thermal stresses because of their huge size, high operating pressure and temperature or, rather, temperature gradients. Optimal performance of boiler feed water pumps has great significance not only for the pump designers and manufacturers but also for the operators of pumps in power plants. In this article, the steady and transient operating conditions of one of the two largest pumps ever built in the world of its kind, installed in the Niederaussem lignite-fired power station Pump simulation

Reliability Prediction of a Return Thermal Expansion Joint
An efficient reliability assessment approach is used to estimate the reliability of a return expansion joint. This component is part of a large power generation system. In order to perform the reliability assessment task, Computational Fluid Dynamics (CFD), Finite Element Method (FEM), Fatigue analysis, and Monte Carlo Simulation (MCS) tools are integrated. The process starts with CFD simulatio...

متن کاملControl Errors in CFD!
Error control in computational uid dynamics (CFD) has been crucial for reliability and e ciency of numerical ow simulations. The roles of truncation and rounding errors in difference approximations are discussed. Truncation error control is reviewed for ODEs. For di erence approximations of PDEs, discretization error control by Richardson extrapolation is outlined. Applications to anisotropic g...
متن کاملEffect of impeller geometry on performance characteristics of centrifugal compressor
Centrifugal Compressors play an essential role in oil, gas and petrochemical industries. Their extensive usage is due to their smooth operation and high reliability compared to other other compressor types. One of the main characteristics of these turbomachines is their performance curve, which is an important criterion for selecting the appropriate compressor for a desired working condition. I...
