dc.description.abstractThis study presents motion of ellipsoidal air bubble in stagnant water through a vertical narrow rectangular channel of 2.1X66.5 mm cross section. Main analysis tool used in the study is image processing. This method appears to be promising for determining the governing mechanisms of the bubble motion. The test section of the facility is one to one scaled model of single cooling channel of TR-2 nuclear research reactor. The automatic bubble generation technique used in this experimental study is shown to have several advantages, e.g. the accuracy of the bubble size, repeatability of tests, and controlling the time between consecutive bubbles. This study focuses on the quantitative assessment of ellipsoidal bubble size (perimeter, area, volume, width and height), shape, path and rising velocity. The range of analyzed ellipsoidal bubbles is 2.1<dae<\53 mm. According to analyses, ellipsoidal bubbles follow sinusoidal path in narrow rectangular channels. Same size ellipsoidal bubbles follow sinusoidal paths with the same amplitude and the same period. In addition, rise velocities of ellipsoidal bubbles in the experimental runs are analyzed and compared with the rise velocity correlation of ellipsoidal bubbles in infinite medium and a new empirical correlation is suggested for rising velocities of two dimensional ellipsoidal bubbles.tr_TR
