V. Hans, Ernst V. Lavante, F. Peters, & V. Vasanta Ram ¡¶Fluid Mechanics for Flow Metering¡· Springer ISBN: 3540222421 1 edition (December 11, 2006) 269 pages PDF 8 Mb Flow meters measure the volumetric flow rate in a pipeline. Most meters are based on deriving a signal from the fluid flow and calibrating the signal against the volumetric flow rate. The calibration is done in fully-developed flow, and the same state of flow must exist at the meter¡¯s position when it is in practical use. Because the field of flow metering has been neglected by fluid mechanicists for a long time, this book addresses two major fluid mechanical problems in flow metering: the analysis of signal generation in turbulent pipe flow, which explains the function of the meter beyond a simple calibration, and the possible use of a meter in non-developed flows. These problems are investigated with reference to, and examples from, a variety of meters, e.g. ultrasound cross-correlation meters, vortex meters, and turbine meters. Studying these problems requires consideration of specific phenomena in turbulent non-developed pipe flow, as caused by installations, and finding special solutions with signal processing, both of which are included in the book. http://rapidshare.com/files/6953008/Fluid_mechanics_of_flow_metering.rar http://depositfiles.com/en/files/1002093 http://mihd.net/nvtoq3 |
