“…Recent examples of design optimization methods are the works of Khalifeh Soltan et al [5], Unuvar and Kargici [6], Selbas et al [7], Sena-Gonzalez et al [8], Ponce-Ortega et al [9], Costa and Queiroz [10], and the optimization techniques utilized nowadays in heat exchangers optimization are frequently of genetic nature [7,11,12,13]. Although some scholars are skeptical about the use of precise optimization methods when applied to heat exchanger design, owing to the inherent fuzziness of the problem given the uncertainty in operating conditions and in the adopted design correlations [14], computer based optimization of heat exchanger design is an established and widely accepted research subject.…”
