Moreover, it was applied to theoretical investigations of pipe flow
, in which pressure was assumed to be a function of the axial distance only and one-dimensional.
Wingate's first volume related to hydraulics, pipe flow
, industrial HVAC, and utility systems, Volume 2 in the Mister Mech Mentor series is a new collection featuring ASME's piping and pressure vessel code applications.
The calculation model is divided into six subprocedures: (1) critical flow through the gap between the disc and seat, (2) injection expansion flow from the gap into the valve house, (3) vapor-liquid two-phase pipe flow
in inlet, outlet, and downstream pipe, (4) vapor-solid two-phase flow in outlet and downstream pipe, (5) sudden expansion pipe flow
, and (6) sudden contraction flow.
HWM Hydreka has introduced the ChronoFLO Transit Time ultrasonic flowmeter, a temporary or semi-permanent device for accurate, real-time pipe flow
measurement and leakage logging.
Written primarily for fluid mechanics scientists but also suitable for postgraduate students and practitioners, the papers cover such topics as techniques of research and results in coherent structures of wallbounded turbulence, results on large eddy simulations of some environmental flows, nearshore mixing and macrovortices, large scale circulation in shallow lakes, multiple states in open channel flow, flow-induced excitations on basic shape structures, air entrainment in vertical dropshafts, variational methods in sloshing problems, scalar dispersing within canopies, flow solvers for liquid-to-liquid impacts and turbulence, friction and energy dissipation in transient pipe flow
The diagonal solid lines represent a full pipe flow
condition for that drain diameter and grade.
It was discovered that in turbulent pipe flow
, the rate of flow at a constant pressure increased as polymer was added to the flow medium, in this case water.
This new service will deliver over 30 regional forecasts in the continental United States, 3 regional forecasts in Western Canada, a Forecast Summary report (8/year), a weekly Natural Gas Production forecast, a Rig Breakout & Actualization report (showing trends and new plays), a weekly Pipe Flow
Analysis update, and a monthly report on the EIA 914 filing.
Tenders are invited for Instrumentation for an ultrasonic/area velocity compound type flow meter for use in applications for pipes that can range from partially full to totally full and will utilize an ultrasonic height transducer mounted in the top of the pipe using a trapezoidal flume installed in the pipe as well as two ultrasonic velocity transducers (TYPE A & TYPE B) for measuring the flow velocity above the range of the trapezoidal flume to full pipe flow
Among specific topics are the numerical simulation and pressure drop prediction of slug flow in oil/gas pipelines, the influence of temperature and electrolyte concentration on regime maps in vertical-adiabatic two-phase pipe flow
, modeling effects of particle size and pipe gradient on sand transport in multiphase pipes, modeling a micrometer-sized molten metallic droplet impact on a solid wall, and the three-dimensional visualization of the natural convection of miscible fluids due to the density difference in a packed bed.
