New paper on rigid and flexible nozzle optimization

Multi-objective Bayesian optimization of rigid and flexible nozzles for energy-efficient pulsed jet propulsion

Paras Singh, Yukesh Karki, Victor Hernandez, Daehyun Choi, Saad Bhamla, Chandan Bose. arXiv (2026).

We used multi-objective Bayesian optimization and 3D fluid-structure interaction simulations and showed flexible nozzles achieve higher propulsive efficiency than rigid ones through FSI-driven pressure recovery mechanisms. Download the paper. Check out the videos in APS Gallery of Fluid Motion.
