Hydraulic Settling of Flushed Swine Manure A Case Study
Applied Engineering in Agriculture, 1987ADAPTION of flushed manure management systems for modern swine production facilities has reduced labor managment problems, but in doing so has created new problems. Typical problems may include odors from lagoons or other liquid storage structures, and the managment of labor and equipment involved with recycling flush water or field applications ...

An effect evaluation method of coal seam hydraulic flushing by EMR
Journal of Natural Gas Science and Engineering, 2018Abstract Present coal seams in China are characterized by great gas pressure and content, low permeability features, and thus, the extraction of gas is difficult and gas disaster remains serious. To improve the permeability of coal seam, the hydraulic flushing is adopted, so the effect evaluation of stree relief and permeability enhancement will be ...

Determination of hydraulic flushing impact range by DC resistivity test method
International Journal of Rock Mechanics and Minings Sciences, 2018Abstract Chinese coal mines often apply hydraulic flushing technology for pressure relief and permeability increase of difficult-to-extract coal seams In order to study effective detection methods for the impact range of hydraulic flushing on coal seams, we first experimentally investigated the response characteristics of the apparent resistivity ...

Analytical estimates of hydraulic parameters for an urbanized estuary – Flushing Bay
Journal of Hydrology, 2007Summary Prediction of water quality improvements in urban estuaries is an urgent priority for decision making about alternative mitigation measures, especially in the context of changing pollutant loadings and freshwater discharges. Flushing Bay, an embayment of the New York–New Jersey Harbor Estuary, is a “short” estuary (a special class of coastal ...

Turbulent flushing of internal pipe-type surfaces in hydraulic components
Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical EngineeringThe cleanliness of hydraulic systems has long been regarded as a crucial indicator of their performance and longevity. This study aims to elevate the cleanliness level of hydraulic components from 500 μm to 300 μm. To achieve this goal, this study integrates the flushing process and establishes a physical and mathematical model of wired solid ...
