This book is about computational science and engineering, with applications in potential theory and in solid mechanics (linear elasticity). Boundary Methods: Elements, Contours, and Nodes presents the results of cutting-edge research in boundary-based mesh-free methods. These methods combine the dimensionality advantage of the boundary element method with the ease of discretization of mesh-free methods, both of which, for some problems, hold distinct advantages over the finite element method. After introducing some novel topics related to the boundary element method (BEM), the authors focus on the boundary contour method (BCM)-a variant of the BEM that further reduces the dimensionality of a problem. The final section of the book explores the boundary node method, which combines the BEM with moving least-squares approximants to produce a mesh-free, boundary-only method. The authors, who are also the primary developers of these methods, clearly introduce and develop each topic. In addition to numerical solutions of boundary value problems in potential theory and linear elasticity, they also discuss topics such as shape sensitivities, shape optimization, and adaptive meshing. Numerical results for selected problems appear throughout the book, as do extensive

Hydraulics of pipeline systems



Pipeline Engineering Reference from C.H.I.P.S.

The first of its kind, this modern, comprehensive text covers both analysis and design of piping systems


Hydraulics of Pipeline Systems begins with a review of basic hydraulic principles, with emphasis on their use in pumped pipelines, manifolds, and the analysis and design of large pipe networks.

After the reader obtains an understanding of how these principles are implemented in computer solutions for steady state problems, the focus then turns to unsteady hydraulics. These are covered at three levels:
- Situations in which inertial forces and elastic effect can be ignored-quasi-steady solutions
- Situations that include inertial forces and techniques for solving systems of equations that describe time-dependent flows and pressures in large networks
- Situations in which time-dependent changes are really rapid-true transient analyses that also include the elastic effect of liquid compression and pipe expansion
