On Bubble Rising in Countercurrent Flow
Original language description
Experiments were performed over a range of Reynolds number 60 <= Re <= 2200, We-ber number 1 <= We <= 14, Tadaki number 1 <= Ta <= 10, Eotvos number 1 <= Eo <= 22, and bubble aspect ratio 0.4 <= b/a <= 0.9. The bubble shape, bubble position and motion were investigated by direct observation of two plane projection of bubble by high speed camera. Typical sampling frequency was 150 fps. Relatively long records, (approximately 9000 frames per one bubble observation) allow us to get relevant statistics of treated data. Bubble aspect ratio has been determined from both projection planes. Dimensionless front area of observed bubble has been introduced as suitable parameter for correlation with Eotvos number. Model of static bubble and classical Wellek correlation were employed as asymptotes. Bubble rising velocity has been determined and tested for each single bubble with respect to liquid properties. Velocity data are plotted within the frame given by several theoretical predictions for pur
