Abstract

The two-phase flow regime characterization by use of wall pressure fluctuation power spectra was proposed by Dr.M.G.Hubbard and Dr.A.E.Dukler to deal with horizontal flow. In this work, the power spectra of various flow regimes of two-phase flow with different inclinations were obtained and analyzed. The effect of inclination of a conduit on power spectra and flow mechanisms was investigated. Also a method of decomposion of power spectra was proposed. The results suggested that a two-phase flow process could be decomposed into several simple processes each of which was represented by an individual spectral component.
