Ultrasonic tomography for multiphase flow regime identification

Abstract

This project presents the application of ultrasonic tomography in the process and chemicals industries. This ultrasonic tomography system is to identify the multiphase flow regime which is liquid, gas and solid at once. This is due to the industry process where up til now no research had been investigate for the multiphase flow that display the tomogram of liquid, gas and solid at once. The transmission mode with fan shaped beam back projection had been implemented. The system also was designing non-invasively in other to provide information about the composition of the system without disturbing the nature of process being examined. In this system, 8 Transmitters and 8 receivers which produce 8x8 projections were implemented. The linear back projection algorithm was implemented for the image reconstruction part. The system also was divided into two parts which are hardware system and software system. In the hardware system, the values of holding voltages were take note because it will use in the software system. Then, the linear back projection algorithm was implemented in the software system in other to get the concentration profile and display the tomogram. The experiments that had been conducted shows that the multiphase flow regime for liquid, gas and solid at once can be identifying by using ultrasonic tomography.
