Finite Elements and Fast Iterative Solvers: with Applications in Incompressible Fluid Dynamics (Numerical Mathematics and Scientific Computation)

The topic of this booklet is the effective resolution of partial differential equations (PDEs) that come up while modelling incompressible fluid circulate. the cloth is geared up into 4 teams of 2 chapters each one, protecting the Poisson equation (chapters 1 & 2); the convection-diffucion equation (chapters three & 4); the Stokes equations (chapters five & 6); and the Navier-Stokes equations (chapters 7 & 8).

Hydraulics in civil and environmental engineering

Now in its 5th version, Hydraulics in Civil and Environmental Engineering combines thorough insurance of the elemental ideas of civil engineering hydraulics with wide-ranging remedy of functional, real-world purposes. This vintage textual content is thoroughly dependent into elements to handle ideas prior to relocating directly to extra complicated issues.

3 Pressure Drop due to Friction In this chapter, we introduce the concept of pressure in a liquid and how it is measured. The liquid flow velocity in a pipe, types of flow, and the importance of the Reynolds number will be discussed. For different flow regimes, such as laminar, critical, or turbulent, methods will be discussed as to how to calculate the pressure drop due to friction. Several popular formulas such as the Colebrook-White and Hazen-Williams equations will be presented and compared.

28) are: Adiabatic bulk modulus=231,426 psi Isothermal bulk modulus=181,616 psi The bulk modulus of water at 70°F is 320,000 psi. 7 Fundamental Concepts of Fluid Flow In this section we discuss fundamental concepts of fluid flow that will set the stage for the succeeding chapter. The basic principles of continuity and energy equations are introduced first. 1 Continuity One of the fundamental concepts that must be satisfied in any type of pipe flow is the principle of continuity of flow. This principle states that the Copyright © 2004 by Marcel Dekker, Inc.
