2.6.2 Data analysis
The proportion of bubbles with particle size ≤50 μm is selected as the test index to analyze the orthogonal experiment results. With the test index as the dependent variable, and pressure, gas-liquid ratio, and length of the release pipe as fixed factors, SPSS19.0 analysis software is used to analyze the orthogonal experiment results of variance analysis and the effects of key process parameters on the micro bubbles.
