Abstract
The goal of this paper is to determine the optimum modes of aquatic locomotion for a tuna-like thunniform swimmer under water, and study the performance of paired thunniform swimmers. The computational framework is developed that couples a high-order fully-resolved numerical simulation of self-propelling flexible thunniform swimmer with the gradient-free optimization procedure based on evolutionary algorithm. The optimization is performed to find the optimum kinematic gaits of a single swimmer which are cost-efficient in start-up propulsion or maintaining constant speed. The performance of a fish pair is investigated under a selected swimming mode with various lateral separation distance under in-phase and anti-phase configuration.
