What is it about?
Unsteady aerodynamic interactions occur between surfaces of an aircraft as it flies through the air. As an aircraft maneuvers during a pitching motion, its wings tend to shed aerodynamic structures that affect surfaces such as the tail located downstream. The work shows how this can be modelled and compared to existing empirical models for validation, and provides an insight on these flow structures.

Why is it important?
The computational simulation considers dynamic motion to capture the effects of an aircraft wing and tail undergoing pitching motion. The physics and interactions between these two surfaces are complicated but critical for assessing aerodynamic behaviors. Our simulation models also agree with empirical data and offer some insight to the these dynamic interactions.
Perspectives
Unsteady wake interactions is a research topic I am interested in. Conducting such simulations is a challenging but rewarding experience. These physical systems are complex, and being able to yield some results that offer information on these aerodynamic processes can be very exciting.
