In the current work, evaluation of thrust performance of flexible caudal fin using Fluid-Structure Interaction (FSI) multiphysics computational analysis is being conducted. The conducted FSI computational analysis is based on experimental work. Thrust performance generated from caudal fin flapping is observed. Effect of stiffness on the thrust performance is observed. Formation of Reverse Karman Street in thrust generation is observed. Phase change due to change of stiffness is observed. While the trends and phenomenon regarding the caudal fin flapping had been confirmed, thrust performance obtained from the FSI model is too low compared to the experimental work and while some plausible root cause had been found, would still need further investigation to determine the exact root cause.
