Optimum Design of Reciprocating Compressors to Meet Thermodynamic Criteria

A mathematical model of a reciprocating compressor is used in conjunction with a "Complex" method of optimisation to determine the "best" dimensions of a single-stage compressor to meet a prescribed duty. The mathematical procedures provide the basic compressor and valve dimensions by optimising an objective function based, in this instance, on criteria of thermodynamic performance. The conseqences of modifying or redefining the objective function " are examined. The effect is investigated of varying the constraints which must be imposed to meet practical considerations. The nature of these constraints, and the limits to be imposed on theM, have to be declared by the designer.
