Hydraulic Modeling And Simulation Of Pumping Systems
MetadataShow full item record
New designs or modifications of existing pump facilities are required frequently in many industries due to new operating conditions, increase in product demand, pump-pipeline interaction issues, pulsation problems, net positive suction head (NPSH) requirements, and so forth. In many cases, hydraulic calculations are carried out by hand, within spreadsheets or using hydraulic simulation tools. Computational tools have become very popular and and practical for simulating the interaction of the different pumping facilities within the pipeline systems as well as defining piping layout and different configurations. However, there is not a well-defined methodology for approaching the diverse types of issues encountered within the industry. A general approach for analyzing some the the typical cases observed in many pumping facilities through hydraulic modeling is presented in this tutorial. The general hydraulic modeling methodology presented will cover various aspects of analyzing a pumping system such as: initial approach, data requirements, hydraulic pipeline modeling, computational fluid dynamics (CFD) modeling, and model validation. The methodology will start from a basic definition of the problem and tools used for this type of analysis. This will assist in defining an optimal path to model and simulate the system. The tutorial will conclude with basic case studies of the pumping systems that will illustrate the application of the methodology, its basic assumptions, results, and limitations.
