ONLINE ANALYSIS OF A RANDOM SIGNAL USING COMPUTER AIDED SYSTEM

Abstract

This paper attempts to describe an effective experimental approach to determine the characteristics of the random signal detected in the two-phase flow. This is a Computer-aided data acquisition system reporting data acquisition and data logging of parameters like root mean square (RMS), time, power spectral density (PSD), histogram and probability distribution of a random signal generated by two-phase flow in a vertical channel. The system employs virtual instrumentation software LabVIEW and data acquisition board (DAQ). The measurement and control are accomplished and integrated into the process by using a computerized data acquisition system (DAQ) and comprehensive virtual instrument (VI), which was developed using the LabVIEW application software and DAQ board. In addition, this system allows for easy modification and enhancement of a virtual instrument by modification of the software program. the areas of Microelectromechanical Systems dynamics of complex heterogeneous mixtures (multiphase, slurries), tribology, microheatexchangers; computer-aided measurement systems of concentration, film thickness and viscosity; turbulence and flow pattern phenomena in mixtures, and analysis and validation of deterministic and random signals.
