Impact of Active Aerodynamic Components on Aerodynamic Efficiency under Varying Conditions
American Journal of Student ResearchGlobal carbon emissions are at an all-time high in part due to gas vehicles. While efforts to switch to more fuel efficient and electric vehicles are prevalent, these efforts are slow. Simple measures to reduce aerodynamic drag through active aerodynamics would increase each individual vehicle’s efficiency, reducing emissions.

Aerodynamic Perspectives on Wind Energy Efficiency
2019This thesis investigates the efficiency of wind energy conversion from three aerodynamic perspectives. The first, purely theoretical, assumes steady inviscid flow conditions to identify multi-rotor setups that can extract more power per unit area than isolated rotors.

On the sensitivity and efficiency of aerodynamic shape optimisation [PDF]
, 2019 Computational fluid dynamics (CFD) has become the method of choice for aerodynamic shape optimisation of complex engineering problems. To date, however, the sensitivity of the optimal solution to numerical parameters has been largely underestimated. Meanwhile, aerodynamic shape optimisation based on high-fidelity CFD remains a computationally expensive

Aerodynamic Design of Efficient Two-Dimensional Channels
Journal of Fluids Engineering, 1953Abstract A general design method is presented for two-dimensional channels with arbitrary prescribed velocity distributions along the channel walls. The design method is developed for compressible or incompressible fluids and is applied to the design of channels with relatively thin boundary layers.
