Verification of an earlier suggested mathematical model of the flow of ceramic paste, describing the velocity conditions in the circular extruder mouth on forming. The verification was carried out by comparing the calculated and experimental velocity profiles, the average velocity of the α-Al₂O₃ paste and the corresponding conditions in the velocity profile. The satisfactory agreement of the model results and experiment has justified the simplifying assumptions and boundary conditions introduced into the mathematical model. |
