Tornado dynamics study using immersed boundary (IB) - Lattice Boltzmann Method (LBM) on a 7-cylinder building configuration
Bibliographic record
Abstract
Tornadoes are disastrous, naturally occurring atmospheric phenomena; they cause fatalities; they damage properties with an exceptional combination of translational and rotational velocities. Despite many studies on tornado-structure interaction, the research papers on tornado-multi-body interactions are limited. This research studies the effects of a tornadic wind on a 7-cylinder building model at several orientations in 2-D using a powerful Immersed Boundary-Lattice Boltzmann Method (IB-LBM). The tornadic wind was simulated by a customized Rankine Combined Vortex Model (RCVM). The wind-loadings on the seven cylinders were quantified using aerodynamic force and moment coefficients. The essential flow features associated with a vortex-structure interaction was investigated in great detail by doing a case study. Then, a unique optimization procedure was utilized to detect individual safe zones for each aerodynamic coefficient. Finally, an overall safe zone for the complete 7-cylinder building model has been ascertained to be between 29° and 69° by analyzing the individual safe zones.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
