Numerical Study of Storm Geyser Mechanism in the Multi-Inlet System at Laboratory and Prototype Scale
Bibliographic record
Abstract
Storm geysers increasingly occur in sewer systems under climate change and rapid urbanization. The geyser mechanism in a single-inlet system has been extensively studied, while the geyser mechanism in multi-inlet systems has yet to be discovered. In this study, three-dimensional computational fluid dynamics models with multi-inlets at laboratory and prototype scale were established to investigate geysering induced by rapid filling. The numerical results at laboratory scale indicate that compared to the single-inlet model under identical inflow conditions (rapid increase the same total flow in the same time), the geyser pressure generated in the multi-inlet model is less than that of a single-inlet model, but more water is ejected out, and the geyser process is closer to the actual geyser event. The numerical results of the prototype model show that the equivalent density of the water-air mixture during geysering in the prototype scale model is about 212 kg/m3, which is less than the equivalent density in the laboratory scale model.

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.
