ACCELERATED AIRFOIL OPTIMIZATION VIA VIBRATIONAL GENETIC ALGORITHM
Transonic airfoil optimization is made for drag minimisation through shock wave reduction. In this study, a new approach to genetic algorithms, called Vibrational Genetic Algorithm (VGA), is used for transonic airfoil optimization.

Numerical Computation of Unsteady Compressible Flow past a Plunging Aerofoil
Unsteady Reynolds-averaged Navier-Stokes (RANS) computations are presented for subsonic and transonic flow past a plunging NACA 64A010 aerofoil. The Implicit RANS solver used for obtaining the time-accurate solution is based on finite volume nodal point ...

Flow characteristics of ejector nozzles with different auxiliary intake valves
The ejector nozzle requires a third auxiliary airflow to improve its thrust performance at transonic speed. However, different auxiliary air intake structures will affect the third auxiliary flow, which in turn may change its thrust performance and ...

Direct nanoscratching with a 500 nm diamond lapping film creates groove‐guided liquid‐crystal alignment interfaces on PCB‐compatible Cu‐patterned RF substrates within minutes, eliminating polymer coating and high‐temperature baking. The coating‐free process enables optical/molecular alignment validation and voltage‐programmable 28 GHz reflection‐phase ...
