About This Video
This Arena-flow simulation provides an internal view of sand compaction and particle movement for a Jacket Core using the Shell Module.
The video explores internal cavity behavior through orthogonal slicing and flux-plane analysis to better understand fill uniformity and blow-time efficiency.
Video layout:
- Left upper: Bulk density slices in the X-direction, revealing how internal regions of the cavity compact during the blow process.
- Left lower: Sand particles colored by species, illustrating particle trajectories and blending as the core fills.
- Right upper: Bulk density slices in the Y-direction, providing complementary insight into internal compaction patterns.
- Right lower: Flux-plane data showing accumulated sand mass (kg) over time (s). The green line marks the end of blow, indicating the cavity is full. In this case, extending blow time beyond ~1.5 seconds offers little additional benefit. Flux planes function like virtual sensors, tracking both air and particle flow across the plane.
Cross-sectional density views and flux tracking confirm efficient cavity filling, providing engineers with key feedback for optimizing blow duration and airflow distribution.
