Reynolds number calculation and applications for curved wall jets [PDF]
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
Truss-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
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.

Numerical Validation of a Multi-Dimensional Similarity Law for Scaled STOVL Aircraft Models
The 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 ...

Laminar-to-Turbulence Transition Revealed Through a Reynolds Number Equivalence
Flow transition from laminar to turbulent mode (and vice versa)—that is, the initiation of turbulence—is one of the most important research subjects in the history of engineering.
