APPARATUS AND METHOD FOR MEASURING PARAMETERS OF A MIXTURE HAVING LIQUID DROPLETS SUSPENDED IN A VAPOR FLOWING IN A PIPE |
摘要 |
<p>An apparatus 10,70 and method is provided that includes a spatial array of unsteady pressure sensors 15 - 18 placed at predetermined axial locations xl -xN disposed axially along a pipe 14.for measuring at least one parameter of a saturated vapor/liquid mixture 12, such as steam, flowing in the pipe 14. The pressure sensors 15 - 18 provide acoustic pressure signals P1(t) - PN(t) to a signal processing unit 30 which determines the speed of sound amix propagating through of the saturated vapor/liquid mixture 12 in the pipe 14 using acoustic spatial array signal processing techniques. The primary parameters to be measured include vapor/liquid concentration (i.e., steam wetness or steam quality), vapor/liquid mixture volumetric flow, mass flow, enthalpy, density and liquid droplet size. Frequency based sound speed is determined utilizing a dispersion model to determine the parameters of interest.</p> |
