Numerical simulation of turbulence interaction noise applied to a serrated airfoil
Turbulent wakes generated by turbofan blades and interacting with the outlet guide vanes are known to bemainly contributing to broadband noise emission of aero-engines at approach conditions. Analytical approaches,such as the well-known Amiet's model can

A numerical study on aerodynamic resonance in transonic separated flow [PDF]
, 2009 An ongoing numerical investigation of unsteady shock/boundary layer interaction on a 2-d supercritical airfoil in transonic flow is presented. Initially, the finitevolume URANS solver DLR-TAU is used to simulate self-sustained periodic shock oscillations

Optimization Approach on Flapping Aerodynamic Characteristics of Corrugated Airfoil [PDF]
, 2018 The development of biomimetic micro-aerial-vehicles (MAVs) with flapping wings is the future trend in military/domestic field. The successful flight of MAVs is strongly related to the understanding of unsteady aerodynamic performance of low Reynolds ...

The quest for a truly parsimonious airfoil parameterisation scheme
, 2008 The conceptual phase of the aircraft design process demands a parsimonious description of the airframe geometry. While there is no hard and fast upper limit on the affordable number of variables, the so-called 'curse of dimensionality' must always be ...

Flat-Plate vs NACA 63A‑010 Airfoil Performance for Subsonic, Low‑Re Rocketry
Flat-plate airfoils are widely used in rocketry for their strength and high manufacturability. However, at subsonic speeds, they incur higher drag from early flow separation and turbulence, leading to unfavorable costs and flight efficiency.

Relative assessment of different turbulence models in prediction of airfoil characteristics for a wide range of angle of attack [PDF]
Simulation of separated flow past an airfoil beyond stall, along with the prediction of stall itself still remains a challenging problem. In practical design and analysis problems of aerodynamics involving turbulent flow, the most widely used ...

, 2013 Busemann bi-plane airfoil concept offers good aerodynamic efficiency at supersonic wave; however it produces more skin friction drag because of its larger wetted area. This makes Busemann bi-plane less effective in subsonic area. To overcome this problem,
