The Power Formula for Atmospheric Stirling Engines 929027

A new proposed formula allows the evaluation of the indicated power of an atmospheric Stirling engine by means of minimum working fluid volume, mean arithmetical pressure difference and correction factors for dead space and compression ratio, grounded on the simplest geometrical and design characteristics.
The practical example given in this paper presents the comparison among the Beale formula and other similar equations, developed by other authors, showing various accuracy.
Closer approximation has been reached by the proposed formula in comparison with other expressions.
