Abstract

fetched live from OpenAlex

Thermal energy transfer in the atmosphere occurs from a high temperature zone to a low one by means of convective vortices where mechanical energy is produced.There are two ways of driving vertical flow in the core of a vortex: (1) by the direct action of buoyancy acting on hot air and (2) by producing a vertical pressure gradient along the axis of a vortex because of core development involving the lateral spread of the vortex with height.In particular, it indicates that the intensity of convective vortices depends on the depth of the convective layer via thermodynamic efficiency, the enthalpy perturbation across them, and the existence of sources of vorticity.The atmospheric vortex engine (AVE) is a device for producing an artificial vortex.The operation of AVE is based on the fact that the atmosphere is heated from the bottom and cooled at the top.By artificial vortex generation, it is aimed to eliminate the physical solar updraft tower and reduce the capital cost of solar chimney power plants.This paper reviews natural convective vortices and vortex creation via physical principles of vortex generation.Vortex analysis and modelling are presented.Furthermore, a new model of a solar vortex engine (SVE) is proposed and discussed.An idea on utilizing the solar energy as the heat source for establishing the vortex and operating the SVE model is adopted.The SVE model is feasible and promising for electrical power generation.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
