Abstract
In many technological units (heating furnaces, kilns, aspiration hoods, etc.), a provision is made to include open ports through which undesirable air can flow. Air curtains have been widely applied to reduce the air flow rate by increasing the drag in these ports. However, this method of reducing the flow rate results in rather high operational cost due to unavoidable loss of electrical energy through air-curtain fans. Structural elements installed in front of the port inlet can provide an alternative. These structural elements ensure the drag increase without shutting off the effective cross section of the ports (in order to ensure implementation of technological operations of aggregate loading, displacement of different-type manipulators, or transport vehicles) and can be implemented with minimum cost. This study objective is to develop a method of mathematical modeling of separated flows upstream of suction slot openings within the SDVM (The discrete vortex method application is known in the stationary set-up framework). With use of discrete vortexes method in stationary statement, mathematical modeling method of detached flow on the input to the flat canals is constructed and discussed. The problem about detached flow on the input to the flat canal with screen is solved. Validity and adequacy of received results are demonstrated by the comparison with calculations, according to the method of N.E. Zukovsky and by experimental data. The developed method of mathematical modeling and computing algorithm of its realization may be used for detection of current available line, velocity field and form loss coefficient of input to the suction ducts, equipped by arbitrary system of thin screens.

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 it
