Abstract: This paper tackles the multi-objective design optimisation and comparative investigation of a cascade organic Rankine-Goswami cycle (ORC-GW) operating with various refrigerants, namely R600, R236ea, and R245fa, in the organic Rankine cycle (ORC). The solution of the multi-objective optimisation problem is achieved by applying the African vultures optimisation algorithm (AVA). The results show that the ORC-GW operating ammonia-water/R600 working fluid pair has increased total cost and second law efficiency compared to its competitors, respectively 24.575 M€ and 0.440.
