Abstract:
A rheological model of a biviscous fluid is proposed, describing laminar and turbulent flows of Newtonian and non-Newtonian fluids in round cylindrical pipes. For low shear rates, common rheological models (Newton, Bingham, Ostwald, Herschel – Bulkley, Shulman – Casson, etc.) are used, and for high rates, a generalization of the L. Prandtl model is used. Taking into account the averaged flow characteristics, a model of turbulent flow and velocity distribution equations in round pipes are constructed. The model ensures the continuity of the dependence of hydraulic resistance on the fluid flow r

Abstract:
The work is devoted to the analysis of the flow of immiscible liquid in a flat channel and the creation of calculation schemes for determining the flow parameters. A critical analysis of the well-known Two Fluids Model was carried out and a new scheme for the determination of wall and interfacial friction, called the hydraulic approximation in the theory of stratified flows, was proposed. Verification of the proposed approximate model was carried out on the basis of a direct numerical solution of the Navier–Stokes equations for each fluid by a finite-difference method with phase-boundary track

Simple fluid pumps have been developed to improve microfluidic device portability, but they cannot be easily programmed, produce repeatable pumping performance, or generate complex flow profiles — key requirements for increasing the functionality of portable microdevices.

Abstract:
Circular hydraulic jumps are familiar in single layers. Here we report the discovery of similar jumps in two-layer flows. A thin jet of fluid impinging vertically onto a rigid horizontal plane surface submerged in a deep layer of less-dense miscible fluid spreads radially, and a near-circular internal jump forms within a few centimetres from the point of impact with the plane surface. A jump is similarly formed as a jet of relatively less-dense fluid rises to the surface of a deep layer of fluid, but it appears less stable or permanent in form. Several experiments are made to examine the case

Abstract:
If a shear flow of a homogeneous fluid preserves the shape of its velocity profile, a standard formula for the condition for hydraulic control suggests that this is achieved when the depth-averaged flow speed is less than (gh)1/2. On the other hand, shallow-water waves have a speed relative to the mean flow of more than (gh)1/2, suggesting that information could propagate upstream. This apparent paradox is resolved by showing that the internal stress required to maintain a constant velocity profile depends on flow derivatives along the channel, thus altering the wave speed without introducing

This paper deals with the propagation of nearly resonant gravity waves in two-layer flows over a bottom topography assuming that both fluids are incompressible and inviscid. Evolution equations are derived for weakly nonlinear surface-layer and internal-layer waves in the hydraulic limit of infinite wavelength. Special emphasis is placed on the flow regime where the quadratic nonlinear parameter associated with internal-layer waves is small or vanishes. For example, this is the case for all possible density ratios if the velocities in both layers are equal and if the interface height is close

Abstract:
In the now-a-day’s methods of hydraulic calculation of pressure collector-pipelines, the value of the coefficient of hydraulic friction (Darci coefficient) is assumed to be constant. However, the fluid flow rate along the collector pipeline is variable. It increases along the pipeline at the expense of fluid inflow from jets through inlets in its wall. In the initial segments of long CP the fluid flow is laminar. Farther, with the increase of fluid flow rate, a turbulent stream is formed. In this paper, laminar streams are considered. The variability of Darci coefficient is taken into account.

Abstract:
One of the most important tasks of engineering hydraulics is to determine the energy loss during the motion of the fluid flow. The study of the question of whether the patterns of hydraulic resistances are similar in a calm and turbulent flow is relevant in the design of hydraulic structures. In most cases, a turbulent regime of fluid motion is observed in various applications, but to date, the theory of turbulence is not considered complete. When designing hydraulic structures, inaccuracies in the existing calculation methods can lead to a decrease in the efficiency and reliability of the ent

Controversial number of phases in debris-flow masses involves almost all areas of debris-flow research.

Fluid escape tests, displacement experiments, relative motion experiments, and rheometrical tests were conducted using 12 slurries prepared with the sediments. The results from four types of experiments show that debris flows are close to one-phase flow and far from two-phase f

Abstract:
Government regulations incentivize investigation of the potential for hybridization of non-road mobile machinery (NRMM). Many approaches to energy saving in hydraulic systems have been established. One of the methods first introduced in the aerospace industry is “decentralized” or “zonal” hydraulics. The decentralized system is realized with pump-controlled actuators, which are distributed throughout the system. In this research, decentralized hydraulics are realized with a direct-driven hydraulics (DDH) drive and implemented on a 1-ton class JCB micro excavator. The original valve-controlled

Abstract:
In the liquids pipeline industry, large horsepower and flow pumps are used to transport liquid along the pipeline. When these pumps are purchased, they are performance tested with water. Performance tests are also sometimes conducted after a pump has been in operation for some time. The performance of a pump is different with water than with a viscous fluid (crude oil). Therefore, the performance results with water are corrected for viscosity. The Hydraulic Institute (HI) developed viscosity correction factors which are used to correct the pipeline pump performance results. These correction fa

Abstract:
Starting from Newton’s laws of motion and viscosity, this book is an introduction to fundamental aspects of fluid dynamics that are most relevant to groundwater scientists. Based on a perspective of driving versus resisting forces that govern the motion of a fluid, the author derives Darcy’s law for flow through porous media by drawing an analogy to Bernoulli’s law for fluid with negligible viscosity. By combining the effects of gravity and pressure, the author identifies hydraulic head as a convenient numerical quantity to represent the force driving groundwater flow. In contrast to the physi
