“…Venturi meters have been employed in various industries for measuring volume flow rates since the late 19th century [ 1 ]. The Venturi effect applications extend beyond flow measurement and include a wide range of uses, including carburettor systems [ 2 ], gasifier systems [ 3 ], steam ejectors [ 4 ], spray nozzles, wind tunnels [ [5] , [6] , [7] , [8] , [9] ], scrubbers [ 10 ], turbines [ [11] , [12] , [13] ], the production of biodiesel [ 14 ], and the harnessing of waste kinetic energy [ 15 ]. Venturi meters offer several advantages over conventional instruments, including simplicity, reliability, and minimal pressure loss.…”

Multiphysical optimization is particularly challenging when involving fluid–solid interactions with large deformations. While analytical approaches are commonly computational inexpensive but lack of the necessary accuracy for many applications, numerical simulations can provide higher accuracy but become very fast extremely costly. Experimental optimization approaches promise several benefits which can allow to overcome these issues in particular for application which bear complex multiphysics such as fluid–structure interactions. Here, we propose a method for an experimental optimization using genetic algorithms with a custom optimizer software directly coupled to a fully automatized experiment. Our application case is a biomimicking fish robot. The aim of the optimization is to determine the best swimming gaits for high propulsion performance in combination with low power consumption. The optimization involves genetic algorithms, more precise the NSGA-II algorithm and has been performed in still and running water. The results show a negligible impact of the investigated flow velocity. A subsequent spot analysis allows to derive some particular characteristics which leads to the recommendation to perform two different swimming gaits for cruising and for sprinting. Furthermore, we show that Exp-O techniques enable a massive reduction in the evaluation time for multiphysical optimization problems in realistic scenarios.
