A new deconvolution method for analysis of probability density distribution spectra observed in gamma-ray interrogation measurements of multi-phase flows [electronic resource] / D.D.S. Liu. Ottawa : Energy Research Program, Energy Research Laboratories, 1984, c1986. v, 31 p. : graphs CANMET report ; 85-8E "November 1984." Title from cover. Issued also in French under title: Nouvelle méthode de déconvolution pour l'analyse des spectres de distribution de la densité de probabilité obtenus lors de mesures d'interrogation aux rayons gamma d'écoulements multiphases. Includes bibliographical references. "A numerical method for the deconvolution of probability density distribution spectra (PDDS) has been developed. It is based on principles of the least square and the Newton-Raphson iteration algorithm. The PDDS were obtained from measurements of multi-phase flows using a gamma-ray interrogation technique developed recently in the Synthetic Fuels Research Laboratory of the Energy Research Laboratories, CANMET in collaboration with the Chalk River Nuclear Laboratories, Atomic Energy of Canada Limited. The deconvoluted PDDS contain information on the hydrodynamic parameters of multi-phase flow phenomena. Fundamental equations for the numerical method were translated into a Fortran program for practical applications. Examples of PDDS deconvolutions for both simulated and observed spectra are given"--Abstract, p. i. Includes abstract in French. gccst Nuclear energy gccst Methodology gccst Measurement Canada.
