Abstract Scope |
Most studies on nozzle clogging simplify their analysis by using symmetric reductions to simulate the clogging. However, this approach overlooks that clogging typically occurs asymmetrically, leading to a significant increase in the roughness of the inner wall of the nozzle. Therefore, this work aims to compare the results obtained using the usual symmetric simplifications with those obtained from a nozzle at the end of its industrial use. The industrial nozzle at the end of its use has been 3D scanned and shows significant geometric reductions in the lower tubular area, the ports, and the pool. The results obtained show that any nozzle reductions have a direct impact on the mold flow patterns. In addition, it was demonstrated that symmetrical reductions are not enough to accurately reproduce the fluid dynamics within the nozzle and mold, as nozzle irregularities strongly influence the meniscus stability. |
