On the other hand, its Carnot efficiency is only 10 percent, one third that of a compressor-based system.
The efficiency of an ideal stirling cycle with regeneration is equal to Carnot efficiency, which has maximum possible theoretical efficiency of all heat engines operating between same temperature limits.
In this study, the parameter [[eta].sub.0] was chosen to be variable; its value spans the range from zero up to Carnot efficiency (0 < [[eta].sub.0] < 1 - [tau]).
This approach enabled them to derive a general expression for the efficiency at maximum power, depending only on the temperatures of the reservoirs, just as the Carnot efficiency. Curzon and Ahlborn's motivation was purely pedagogical and at the time they were probably not aware that the same expression had been published already in 1957 by Novikov [2] (the original paper in Russian was published in 1957) and by Chambadal [3].
Hydrogen burning MHD generators with their 85% + carnot efficiency are ideal to get a leg up on this system.
Researchers have reported efficiencies of laboratory-constructed devices using this technology of between 15% and 80% of maximum Carnot efficiency.
Given are also values of the Efficiency and Carnot Efficiency ratio ([eta]/[[eta].sub.c]) for the same values of corresponding cycle's high [T.sub.H] and low temperatures [T.sub.L].
One of the key merits of FCVs is high power-generation efficiency, because unlike a normal generation system, the system does not depend on the Carnot efficiency peculiar to thermo motors.
Diesel's patent called for a ratio of over compression ratio of 50:1 or what was necessary for the peak air temperatures dictated by his Carnot efficiency obsession.
