Abstract : A computerized mathematical model of Rankine cycle performance analysis, component design, fluid thermodynamic and thermophysical property evaluation integrated with a multivariable optimization technique, was used to describe the sensitivity of the major system variables of initial cost weight, volume and performance over a .5 to 5 kwe power range to the independant fluid and system variables. These independant variables were automatically and simultaneously operated upon in a continuous manner to effect minimization of a criterion function defined as a weighted summation of the major system variables.
