Application of computer aided system for statistical analysis of experimental data

摘要

This paper presents the results and analysis of in-situ air and water velocities, concentration and their impact on other parameters of multi-phase flow such as flow patterns. Experimental data of in-situ physical parameters such as spatial concentration, mixture velocities, and pressures are presented in time, amplitude and frequency domains. These experiments were conducted in a developed system, which includes a vertical square shaped channel with computer aided measurement systems, interfaced with a CADAS (Computer Aided Data Acquisition System), in which both in-situ concentration and flow patterns influence the characteristics in time, amplitude, and frequency domains of in-situ spatial concentration, pressure gradient, and pressure which have demonstrated vast potential for use as flow pattern discriminator. Distribution of amplitude and frequency established substantial difference between in-situ spatial concentration signals and both pressure signals.
