Available in PDF, EPUB and Kindle. Book excerpt: Particle image velocimetry, or PIV, refers to a class of methods used in experimental fluid mechanics to determine instantaneous fields of the vector velocity by measuring the displacements of numerous fine particles that accurately follow the motion of the fluid. Although the concept of measuring particle displacements is simple in essence, the factors that need to be addressed to design and implement PIV systems that achieve reliable, accurate, and fast measurements and to interpret the results are surprisingly numerous. The aim of this book is to analyze and explain them comprehensively.

Download or read book The Effect of Pressure Pulsations and Vibrations on Fully Developed Pipe Flow written by Donald O. Barnett and published by . This book was released on 1981 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis is presented of the effect of longitudinal pressure pulsations or vibrations on the velocity distribution in laminar or turbulent fully developed pipe flow. Specifically, the Reynolds equations are formulated in a noninertial reference frame so that the influence of pressure pulsations, vibrations, or a combined pressure and vibrational oscillation can be obtained from a single solution. For axisymmetric developed flow of a constant property (incompressible) fluid, the radial and circumferential momentum equations can be solved and the axial momentum equation is linearized so that the velocity field can be obtained as the sum of a steady and a time-dependent component. By obtaining a solution for the case where the pressure (or amplitude of vibration) varies sinusoidally, one obtains the solution for disturbances of arbitrary waveform through a Fourier series expansion of the disturbance. Results are presented that show that the velocity field is dependent upon the mean flow Reynolds number, a vibrational Reynolds number, and the amplitude of the forcing function. In general, the fluid response to differing waveforms is similar to that obtained for simple harmonic oscillations with respect to the various parameters explored.

Download or read book Turbulent Flow in a Porous Tube with Wall Suction written by Manouchehr Heidarpour and published by . This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examines the effects of suction (i.e. lateral flow through the walls) on the structure of a fully developed turbulent pipe flow. Also the effect of suction on pressure gradient and pressure change is examined experimentally. The frictional characteristics of Irrigro$\sp{\circler,}$ the porous tubing used in this investigation, is studied by means of a comprehensive experimental program that considered different lengths of porous tubing. Three aspects of flow in porous pipes are investigated in this study, (i) a computational study of the effects of suction on the flow characteristics, (ii) an experimental study of the frictional characteristics of the porous tubing with no suction condition and (iii) an experimental study of pressure change along a porous tubing with lateral flow. The numerical study of turbulent pipe flow with wall suction rates ranging from A = 0 to 13 percent showed that in fully developed pipe flow, wall suction results in a more uniform velocity distribution with increased near-wall velocity values and reduced velocities near the centerline. The near-wall component of radial velocity, $\nu,$ increases with increasing distance from the wall in the zone near the pipe wall. The absolute levels of turbulent kinetic energy decrease with increasing suction rate. Wall suction increases the wall shear stress, $\tau\sb{\rm w},$ along the wall of the tube. The increase in $\tau\sb{\rm w}$ is significant even for the smallest suction rate (up to 30 percent) while such an increase is much higher for A = 13 percent (up to 360 percent). Analysis of the experimental friction loss data obtained for small diameter porous tubing in this study confirmed that the Colebrook and White (C-W) equation is a very accurate predictor of the friction factor for porous tubing with small diameter size and Reynolds numbers less than 100,000. These results are in agreement with the results of Aggarwal et al (1972). The value of the relative roughness obtained in this study showed that the porous tubing under study is smoother than most of the tubing used as laterals in the traditional trickle irrigation. Also, the fact that the friction factors agreed with the Colebrook-White law indicates that the physical roughness in the porous tubing under study corresponds very nearly to the equivalent sand roughness with a relative roughness of about e/D = 0.002. A relationship was established as a convenient and accurate head loss prediction equation (within 5% error) by combining a power function with the Darcy-Weisbach equation. The combination equation is correctable for viscosity changes and accurate for the porous pipe tubing under study. A pressure change and a pressure gradient prediction relationship were established in the transition zone of the Moody diagram for high suction rates, assuming a uniform radial flow rate along the suction region. The relationships presented herein are based on a control volume approach analysis and incorporated the data obtained from laboratory studies on the porous tubing under study.
