Comparison of airflow-uniformity in different ceiling-diffuser designs with various concentric circles in shrimp freezer using CFD
Abstract
This study presents airflow patterns in the air chamber of a shrimp freezer by using computational fluid dynamics (CFD) simulations made with SC/Tetra V.13 software. The quality of the product depends on the duration of the freezing time and airflow-uniformity. The objective of this study is to improve the airflow pattern by simulating and analyzing the airflow distribution in the air chamber of a shrimp freezer with different designs of ceiling diffuser, with various concentric circles. The results from the simulations show that the ceiling diffuser with 5 concentric circles improves airflow-uniformity at the outlet by 13.57% in SD compared to the original model, resulting in a reduced freezing time.
