Abstract
This study presents a comprehensive Computational Fluid Dynamics (CFD) investigation to
optimize the hydrodynamic performance of a Remotely Operated Vehicle (ROV) designed for
underwater applications. Inspired by the morphology of the ray fish, three design iterations were
analyzed—initial, biomimetic, and manufacturable-final—to assess thrust generation, drag
force, pressure distribution, and velocity streamlines across various flow regimes. Using ANSYS
CFD and the SST k-ω turbulence model, each configuration was tested at velocities ranging from
0.5 m/s to 10 m/s. Results demonstrated a progressive reduction in drag force from 25.85 N in
the initial design to 14.13 N in the final model at 1 m/s, alongside a pressure drop from 550 Pa
to 400 Pa. The final biomimetic design, divided into modular sections for ease of manufacturing,
achieved an optimal balance between performance and constructability. Moreover, the dome shaped front improved high-speed fluid dynamics but was substituted with a flat face due to
fabrication challenges. Pressure contour and streamline analysis confirmed enhanced stability
and reduced turbulence in the final design. This work highlights the critical role of CFD in the
hydrodynamic refinement of ROVs and demonstrates how biomimicry and engineering
pragmatism can converge to yield efficient and feasible underwater systems.
