Hydraulic conductivity of materials such as plants, soil and rocks is defined as the ability of the fluid to pass through pores, spaces or fractures. Saturated hydraulic conductivity is the ratio of volume flux to hydraulic gradient yielding a quantitative measure of a saturated soil's ability to transmit water when subjected to a hydraulic gradient. The level of hydraulic conductivity relies on many factors such as the intrinsic permeability of the material, the degree of saturation, and the density and viscosity of the fluid. There are two approaches that are used for the determination of hydraulic conductivity. In the first approach, the empirical approach, hydraulic conductivity is associated with soil properties such as pore size and particle size (grain size) distributions, and soil texture. In the second approach, the experimental approach, the hydraulic conductivity is determined from hydraulic experiments using Darcy's law. This book contains some path-breaking studies related to hydraulic conductivity. The topics included herein are of utmost significance and will provide incredible insights to the readers.
This book provides a comprehensive overview of boundary layer flows, including laminar and turbulent flows. Chapters discuss such topics as the nature of transition, the effect of two-dimensional and isolated roughness on laminar flow, and progress in the design of low-drag airfoils. They also present theoretical and experimental results in boundary layer flows and discuss directions for future research.
The book is targeting students and professionals who are looking to advance their fluid power careers. The book is colored and has the size of standard A4. This book is the third in a series that the author plans to publish to offer separate book for every hydraulic component. This book introduces knowledge foundation about hydraulic transmission lines. This book overviews the basic types, contamination control, safety, maintenance, troubleshooting, failure analysis, noise control, and modeling of hydraulic transmission lines.
Emerging Technologies in Hydraulic Fracturing and Gas Flow Modelling features the latest strategies for exploiting depleted and unconventional petroleum rock formations as well as simulating associated gas flow mechanisms. The book covers a broad range of multivarious stimulation methods currently applied in practice. It introduces new stimulation techniques including a comprehensive description of interactions between formation/hydraulic fracturing fluids and the host rock material. It provides further insight into practices aimed at advancing the operation of hydrocarbon reservoirs and can be used either as a standalone resource or in combination with other related literature. The book can serve as a propaedeutic resource and is appropriate for those seeking rudimentary information on the exploitation of ultra-impermeable oil and gas reservoirs. Professionals and researchers in the field of petroleum, civil, oil and gas, geotechnical and geological engineering who are interested in the production of unconventional petroleum resources as well as students undertaking studies in similar subject areas will find this to be an instructional reference.
