This chapter discusses the fluid flow in pipes. Problems concerned with the flow of water in pipes are usually solved by either the Darcy formulae or the Maurice Levy formulae. When water, juices, or syrups are transported in the factory, by means of a pump, or even for a short ...
The principle of conservation of the fluid flow rate is why tap jets decrease their section while falling (figure 2): the falling liquid accelerates due to gravity, thus the section of the flow decreases proportionally. In this section, we have focused on real or virtual pipes of finite dimen...
In this paper, we investigate an initial-boundary value problem for a linear Euler-Bernoulli beam equation governing the dynamics of pipes conveying fluid. The fluid flow velocity inside the pipe is assumed to have a small amplitude and to be time-varying, that is,, where a two time-scales ...
1.1.1Single-phase flow In this section, the challenges in modeling of single-phase flows are discussed. One of the well-known fundamental challenges, which have puzzled the scientists and engineers over hundreds of years, is turbulence. Turbulence is frequently described as ‘eddies’ of varying ...
Since fluid flow problems usually treat a fluid crossing the boundaries of a control volume, the control volume approach is referred to as an “open” system analysis, which is similar to the concepts studied in thermodynamics. There are special cases in the nuclear field where fluid does not ...
The investigated CMF geometry is depicted in Figure 4. The CMF geometry consists of a flow divider that distributes the incoming mass flow in two U-shaped measuring pipes. After the flow passed both measuring pipes, a flow combiner unite the streams. The oscillation of the measuring pipe is ...
(Massachusetts Institute of Technology, 2006), outline the main difference between pipe flow and open-channel flow: "flows in closed conduits or channels, like pipes or air ducts, are entirely in contact with rigid boundaries," while "open-channel flows, on the other hand, are those whose ...

The present invention relates to a fluid flow regulator and relates particularly, although not exclusively, to an anaesthesia gas flow regulator. Anaesthetic gases are usually administered through a "circle". This means that two pipes link the patient with the gas flow regulator, one carrying gas ...
Oil flow in pipes, air flow around an airplane wing, sailing submarines and blood flows in arteries are all some examples on fluid flows systems. Since the 1970s, shape optimization of fluid flows systems have captured wide attention over the years for example to obtain minimum drag wing profi...
