Descrição: dc.descriptionIncreasing heat transfer in heat exchangers remains an important research topic for industrial and residential applications. The usage of passive techniques remains a reference due to the lower costs, however, increasing the heat transfer in laminar flow with low-pressure loss remains a challenge. The objective of this paper is to perform a constrained optimisation of a twisted-tape inside a circular tube at low Reynolds number. Twisted tape pitch (P), length (L), translate (T), and twisted tape radius (R1 and R2) were submitted to optimisation. The flow is steady-state, laminar and incompressible. The NSGA-II is the method used for the optimisation procedure. The optimisation process found an optimal twisted-tape geometry with an asymmetric shape for both Reynolds numbers, corresponding to a global heat transfer increase of approximately 90% for Reynolds number 300 and 170% for Reynolds number 600, while for symmetric twisted-tape with ratio 4 (R4) is 57% and 52%, respectively.-
