In this study, we minimize the drag coefficient caused by a bluff body by optimizing the shape variables of the bluff body by means of Extremum-seeking. We consider two cases: Single Input Single Output (SISO) system with only one shape variable and Dual Input Single Output (DISO) system with two shape variables. For SISO Extremum-seeking, we compare with the result of SISO Genetic Algorithm (GA). As a result, we successfully optimized the bluff body shape and reduced the drag. The computational cost of SISO Extremum-seeking and DISO Extremum-seeking is found to be less than 96% and 92% of SISO GA respectively.
