Plunging Airfoil: Reynolds Number and Angle of Attack Effects
Aerospace, 2021 Natural flight has consistently been the wellspring of many creative minds, yet recreating the propulsive systems of natural flyers is quite hard and challenging.

Lagrangian controllability at low Reynolds number [PDF]
, 2016 In this paper, we establish a result of Lagrangian controllability for a fluid at low Reynolds number, driven by the stationary Stokes equation. This amounts to the possibility of displacing a part of a fluid from one zone to another by suitably using a ...

Reynolds number calculation and applications for curved wall jets [PDF]
INCAS Bulletin, 2014 The current paper refers to the preliminary estimation of the Reynolds number for curved wall jets. This, in turn, can be a useful tool for controlling the boundary layer mesh size near a generic curved wall which is wetted by a thin, attached jet.

Geometrically Nonlinear Static Analysis of High-Aspect-Ratio Truss-Braced Wing
Engineering ProceedingsTruss-braced wings (TBWs) feature higher aspect ratios with a lighter weight and lower bending moment than conventional wings. These wings show significant potential for performance improvements in terms of fuel efficiency.

Low Reynolds Number Rotor Blade Aerodynamic Analysis
MATEC Web of Conferences, 2019 Maintaining a steady hover flight in a rotorcraft usually requires high energy input. The aim of the paper is to prove that it is possible to vastly reduce energy use in a rotorcraft by reducing the disc loading.

Self-similar decay of high Reynolds number Taylor-Couette turbulence [PDF]
, 2016 We study the decay of high-Reynolds number Taylor-Couette turbulence, i.e. the turbulent flow between two coaxial rotating cylinders. To do so, the rotation of the inner cylinder (Re$_i=2 \times 10^6$, the outer cylinder is at rest) is stopped within 12 ...

Numerical Validation of a Multi-Dimensional Similarity Law for Scaled STOVL Aircraft Models
AerospaceThe complex jet-ground interactions of Short Take-off and Vertical Landing (STOVL) aircraft are critical to flight safety and performance, yet studying them with traditional full-scale wind tunnel tests is prohibitively expensive and time-consuming ...
