Computer analysis of Stirling engines
The analysis given applies to reciprocating machines that are based on a regenerative thermal cycle. Included are closed-cycle Stirling engines, refrigerators and heat pumps, related free piston machines, cryogenerators, pressure generators, and Vuilleumier machines. Regenerative reciprocating gas machines are high-efficiency, open- or closed-cycle mechanisms either for converting heat energy into mechanical or pneumatic power, or alternatively for elevating heat energy to a higher temperature level through an expenditure of mechanical work or heat energy. Finally, they may perform several of these operations simultaneously. The computer program described realistically simulates the behavior and the characteristics of a regenerative closed-cycle machine, both in steady-state and transient operation. However, substantial programming effort and a large-scale digital computer, such as an IBM 360/65, were required. Output from the program included both parametric variations and single-valued characteristic criteria (run/no run condition, efficiencies, specific output, etc.). The program structure allows planned parametric studies for developing a superior machine. Either an intuitive trial-and-error approach or a sophisticated system transfer function analysis can be used to describe frequency responses of the principal output parameters as a function of variations in the design parameters.
