Available in PDF, EPUB and Kindle. Book excerpt: Millions of dollars are spent each year on water distribution systems. Pipe optimization techniques provide an opportunity for potential savings in costs for water supply systems. These optimization techniques include linear programming, non-linear programming, dynamic programming, enumerative approaches, and genetic algorithms. The former four techniques have been applied to pipe network optimization in the research literature over the last 20 years or so. Genetic algorithms provide a new approach to pipe network optimization. Details of this method are considered in this thesis. A global cost analysis of each component in a water supply system is carried out of the genetic algorithm in order to assess the form of the objective function. Traditionally, the analysis an pipeline systems has focused on the steady state. In the current work, a genetic algorithm optimization model, which uses a probabilistic search procedure that emulates Darwinian natural selection, is coupled with a transient hydraulic simulation model to generate and evaluate trial pipe network designs in search of an optimal solution. A new and powerful penalty function is also developed for pressure violations distinguishing steady state and transient conditions. The genetic algorithm search is applied to a case study which demonstrates its flexibility and the opportunity for significant cost saving offered by this method.

Download or read book Optimization Design by Coupling Computational Fluid Dynamics and Genetic Algorithm written by Jong-Taek Oh and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Nowadays, optimal design of equipment is one of the most practical issues in modem industry. Due to the requirements of deploying time, reliability, and design cost, better approaches than the conventional ones like experimental procedures are required. Moreover, the rapid development of computing power in recent decades opens a chance for researchers to employ calculation tools in complex configurations. In this chapter, we demonstrate a kind of modern optimization method by coupling computational fluid dynamics (CFD) and genetic algorithms (GAs). The brief introduction of GAs and CFD package OpenFOAM will be performed. The advantage of this approach as well as the difficulty that we must tackle will be analyzed. In addition, this chapter performs a study case in which an automated procedure to optimize the flow distribution in a manifold is established. The design point is accomplished by balancing the liquid-phase flow rate at each outlet, and the controlled parameter is a dimension of baffle between each channel. Using this methodology, we finally find a set of results improving the distribution of flow.

Available in PDF, EPUB and Kindle. Book excerpt: Mathematical optimization is the selection of the best element in a set with respect to a given criterion. Optimization has become one of the most used tools in control theory to compute control laws, adjust parameters (tuning), estimate states, fit model parameters, find conditions in order to fulfill a given closed-loop property, among others. Optimization also plays an important role in the design of fault detection and isolation systems to prevent safety hazards and production losses that require the detection and identification of faults, as early as possible to minimize their impacts by implementing real-time fault detection and fault-tolerant systems. Recently, it has been proven that many optimization problems with convex objective functions and linear matrix inequality (LMI) constraints can be solved easily and efficiently using existing software, which increases the flexibility and applicability of the control algorithms. Therefore, real-world control systems need to comply with several conditions and constraints that have to be taken into account in the problem formulation, which represents a challenge in the application of the optimization algorithms. This book offers an overview of the state-of-the-art of the most advanced optimization techniques and their applications in control engineering.

Download or read book SURGE ANALYSIS AND THE WAVE PLAN METHOD written by Srinivasa Lingireddy and published by KYPipe LLC. This book was released on 2021-06-14 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book describes the causes and effects of transient (water hammer) events in liquid-filled pipes, and describes how the powerful and stable Wave Plan Method (WPM) can be used to address transients during surge modeling. The authors compare and contrast WPM with the Method of Characteristics (MOC), which is the other widely-used surge analysis tool. While MOC can be useful for many situations, the larger and more complex a model becomes, the more the computational efficiency of WPM is necessary to avoid longer and longer analysis times. The authors also describe how WPM is more generalizable than MOC, which is a term that describes a suite of tools consisting of several variants that were developed to address different modeling situations. This book provides details on surge modeling in general and the use of WPM in particular. This includes pressure attenuation, determination of wave speeds in different pipe types and various liquid media, pump and turbine characteristics curves, and the effects of boundary conditions. The discussion of boundary conditions includes an extensive look at the effects of the air-water interface as it applies to bulk air intrusion into pipelines, and as it relates to the use of air/vacuum valves as surge protection. The authors discuss surge protection design for different real-world scenarios, and how to model of a full list of surge control devices, including a detailed discussion of check valves. Last, the book describes the assumptions and uncertainties encountered during data collection and model building, and examines the potential effect of these uncertainties. Where uncertainties cannot be mitigated, the authors discuss ways to increase the safety factor of surge protection designs.

This book was released on 2012-03-02 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy has been an inevitable component of human lives for decades. Recent rapid developments in the area require analyzing energy systems not as independent components but rather as connected interdependent networks. The Handbook of Networks in Power Systems includes the state-of-the-art developments that occurred in the power systems networks, in particular gas, electricity, liquid fuels, freight networks, as well as their interactions. The book is separated into two volumes with three sections, where one scientific paper or more are included to cover most important areas of networks in power systems. The first volume covers topics arising in electricity network, in particular electricity markets, smart grid, network expansion, as well as risk management. The second volume presents problems arising in gas networks; such as scheduling and planning of natural gas systems, pricing, as well as optimal location of gas supply units. In addition, the second volume covers the topics of interactions between energy networks. Each subject is identified following the activity on the domain and the recognition of each subject as an area of research. The scientific papers are authored by world specialists on the domain and present either state-of-the-arts reviews or scientific developments.
