This study presents a multifidelity, multi-objective optimization framework for the aerodynamic design of airfoils operating at [Formula: see text] Reynolds numbers in incompressible flow. The framework couples the efficiency of the panel solver XFOIL with the accuracy of the unsteady Reynolds-averaged Navier–Stokes so...

This study presents a combined numerical–experimental investigation of a quasi-static trailing-edge morphing strategy to enhance the aerodynamic performance of vertical axis wind turbines (VAWTs), with emphasis on power coefficient (Cp) improvement and wake evolution. A hybrid airfoil consisting of 60% rigid and 40% fl...

This study presents a manufacturability-oriented aerodynamic design workflow for a 10 kW horizontal-axis wind turbine blade. Thirty-five NACA-series airfoils were screened using the Robust Envelope Minimax with Smoothness (REMUS) framework, which ranks candidates according to regret, robustness, drag-bucket width, and...

Abstract This paper presents a CFD study of thrust-augmenting ejector nozzles for small turbojet engines, motivated by the theoretical prediction of Alperin and Wu that a substantial thrust increase is attainable at moderate subsonic flight speeds via a so-called “second solution” in which the flow at the exit of the m...

Archimedes Spiral Wind Turbines (ASWTs) are suitable for small-scale urban wind applications, but changing the blade angle can also change the rotor dimensions under different geometric constraints. This study examines these coupled effects by comparing five ASWT configurations with blade angles of 30°, 45°, and 60° un...

Rotary-wing platforms have been instrumental in the advancement of modern aviation given their unique vertical take-off and landing (VTOL) capabilities. Their applications vary in both scope and scale to include search and rescue, transport logistics, medical evacuation and surveillance and reconnaissance to name b...
