In this exploration of bioinspired hydrofoil design, we delve into the world of oarfish skin tubercles, seeking to understand if the natural adaptations have inspired the development of hydrofoils with enhanced hydrodynamic performance. Notably, tubercles discovered on the fins and head of humpback whales have showcased their effectiveness in reducing drag and increasing lift. The oarfish skin tubercles exhibit a resemblance to those of humpback whales but on a smaller scale, covering the entire body of the fish. By using a well-preserved oarfish sample we conducted CT scanning and used the generated 2D slices to build a detailed 3D model. This 3D model served as the basis for crafting a bioinspired hydrofoil. The hydrofoils were 3D printed by using Carbon M1 printer. In our investigation of the impact of skin tubercles on hydrodynamic performance, we conducted measurements of lift and drag forces on two distinct hydrofoils: a reference hydrofoil with a smooth surface and an oarfish skin-inspired hydrofoil. We measured these forces with different angles of attack in the flow speed-controlled flume. The preliminary findings suggest that

the bioinspired hydrofoil demonstrates improved hydrodynamic performance.
