개선된 EIT 영상복원 알고리즘을 이용한 2상유동의 기포분포 가시화 연구 = A Study on the Bubble Visualization using the Improved EIT Image Reconstruction Algorithm

다국어 초록 (Multilingual Abstract)

A preliminary investigation is introduced to demonstrate the feasible potentials of the application of the EIT (electrical impedance tomography) to visualize the bubble distribution in two-phase flow. We expect the necessary experimental apparatus for the EIT bubble distribution measurement to be rather simple thus much cheaper than the other bubble motion measuring devices like the LDV(laser doppler velocimetry). PIV(particle image velocimetry) and optical probes. At the present stage, however, the EIT visualization of the bubble distribution takes too long time to be implemented practically. In this paper, an adaptive mesh grouping method based on fuzzy-GA is introduced to reduce the image reconstruction time. Sample reconstructed images by the proposed method are presented with discussion for several's artificial bubbles.
