Abstract(in Japanese) (See Japanese page)
Abstract(in English) New type of gas/odor flow visualization system has been developed. An animated gas/odor flow can be easily obtained using a 5×5 homogeneous QCM gas sensor array. When we used pulse drive semiconductor gas sensors in the previous study, the recovery time was too slow to extract the flow direction from the image. Then, miniaturized QCM gas sensors with internally installed oscillators were used. Since they have fast recovery time enough to detect instantaneous gas concentration change, clearer image was expected to be obtained. The odor flow of triethylamine with small could be successfully visualized almost every time in the wind tunnel in the present study. Moreover, the gas flow direction obtained by an image processing algorithm almost agreed with true one.
