The bubble behavior in non-Newtonian fluid plays a key role in such diverse fields as waste water treatment, petroleum processing, fermentation, polymer devolatilization, composites processing, boiling, plastic foam processing and environment remediation. Polyacrylamide(PAM) is widely applied in industrial processes and biomedicine material; its foundational characteristic has been sufficiently understood. In this paper, PAM aqueous solution was used to study the behavior of bubble formation as...
