Bio-inspired variable-stiffness flaps for hybrid flow control, tuned via reinforcement learning
Nirmal J. Nair, Andres Goza
A bio-inspired, passively deployable flap attached to an airfoil by a torsional spring of fixed stiffness can provide significant lift improvements at post-stall angles of attack.…
Fluid-structure interaction of a bio-inspired passively deployable flap for lift enhancement
Nirmal J. Nair, Andres Goza
Birds have a remarkable ability to perform complex maneuvers at post-stall angles of attack. The passive deployment of self-actuating covert feathers in response to unsteady flow s…
A strongly coupled immersed boundary method for fluid-structure interaction that mimics the efficiency of stationary body methods
Nirmal Jayaprasad Nair, Andres Goza
Strongly coupled immersed boundary (IB) methods solve the nonlinear fluid and structural equations of motion simultaneously for strongly enforcing the no-slip constraint on the bod…
Leveraging reduced-order models for state estimation using deep learning
Nirmal J. Nair, Andres Goza
State estimation is key to both analyzing physical mechanisms and enabling real-time control of fluid flows. A common estimation approach is to relate sensor measurements to a redu…
Transported snapshot model order reduction approach for parametric, steady-state fluid flows containing parameter dependent shocks
Nirmal J. Nair, Maciej Balajewicz
A new model order reduction approach is proposed for parametric steady-state nonlinear fluid flows characterized by shocks and discontinuities whose spatial locations and orientati…
