Abstract

fetched live from OpenAlex

The irreversible cycle model of a regenerative intercooled modified Brayton cycle heat engine has been established for the finite heat capacities of external reservoirs. The power output has been optimized with respect to the cycle temperatures and the optimum performance parameters are calculated for a typical set of operating condition. It is found that there are optimal values of the intercooling and cycle pressure ratios as well as the turbine outlet temperature at which the cycle attains the maximum performance but the optimal values of these parameters are different for different cycle parameters such as the intercooling and cycle pressure ratios, turbine outlet temperature, etc. Moreover, the design problems of some important parameters are discussed in detail, and consequently, the optimum criteria for the intercooling and cycle pressure ratios and the turbine outlet temperature are obtained. The results obtained here are general and some important conclusions in the relevant references may be directly derived from this paper.

Teacher imitation

Not 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.
