Modeling Freely Flying Insects Using A Strongly Coupled High Fidelity Numerical Framework, Jeremy A. Pohly Jan 2023

Modeling Freely Flying Insects Using A Strongly Coupled High Fidelity Numerical Framework, Jeremy A. Pohly

Dissertations

Flying insects, with their remarkable abilities, serve as fascinating sources of inspiration. Deciphering the complex mechanisms that enable monarch butterflies to migrate nearly 80 million times their body length, requires advanced modeling tools. These tools must capture the interplay between non-linear wing aerodynamics, dynamic body responses, and flexible wings, characteristics of the monarch. A novel framework is introduced that tightly integrates these physical phenomena through a dynamic relaxation scheme. The model’s application extends to examining the longitudinal flight of monarch butterflies and the hovering flight of fruit flies, bumblebees, and hawkmoths.
