Computational Fluid Dynamics Analysis in Biomimetics Applications: A Review from Aerospace Engineering Perspective

This overview looks at how Computational Fluid Dynamics (CFD) helps turn biological ideas into aerospace designs. By copying the ways birds, insects, and fish move, biomimetics can cut drag, boost lift, and lower noise. Turning the flexible, complex shapes found in nature into computer models is still a big computational hurdle. The review organizes the steps for using advanced CFD tools—like dynamic meshing, fluid‑structure interaction (FSI), and turbulence models such as LES and URANS—to capture the unsteady flow around flapping wings, shape‑changing surfaces, and micro‑air vehicles (MAVs). Studying flow patterns, pressure fields, and vortex behavior lets researchers improve both aerodynamic performance and structural strength. It also points out that high‑performance

computing now makes simulations more accurate and cheaper than traditional wind‑tunnel tests. However, the source paper notes a gap: there is still a lack of detailed experimental data for many specific animals, so more validation work is needed. The material gives M.Tech students clear guidance on picking biomimetic CFD topics, setting up boundary conditions, and choosing the right solver settings.
