DEVELOPMENT OF TIME-AVERAGED X-RAY CT SYSTEM FOR MEASURING GAS-LIQUID TWO-PHASE PIPING FLOW
摘要
We have developed a noncontact, nondestructive void fraction measurement system on the basis of three-dimensional X-ray CT with the aim of fully understanding the behavior of high-velocity, high-pressure gas-liquid two-phase flow in piping. To measure the void fraction in the flow at high velocity, the time-averaged CT image acquisition by a multiple averaging method was proposed. It was confirmed that the time-averaged CT image was obtained by the captured image of a sample rotating at a high speed in this system. Furthermore, we measured the void fraction in high-velocity, high-pressure piping and confirmed that the proposed method performed as expected even under actual conditions from a comparison result obtained with a differential pressure gauge.
