| Abstract: |
| Bubble rising behavior is studied mainly through the combination methodology of model calculation and experimentation in this paper.Based on Newton's laws of motion,the differential equation of bubble rising behavior for different physics models are established;the values of key factors of bubble rising behavior are assumed and used to derive the prediction formula of the bubble rising behavior parameters.The adaptability analysis and numerical calculation are carried out for different flow patterns.The bubble rising behavior experiment has also been designed to illustrate the adaptability analysis and to amend the key parameter value.Bases on these results,a new method for the bubble rising behavior and determining the corresponding parameter values is presented in this paper. |
