Interpretation of Four Unique Phenomena and the Mechanism in Unsteady Flow Separation Controls

Energies, 2019
Unsteady flow separation controls are effective in suppressing flow separations. However, the unique phenomena in unsteady separation control, including frequency-dependent, threshold, location-dependent, and lock-on effects, are not fully understood ...

Delayed Detached-Eddy Simulations of Aerodynamic Variability During Carrier-Based Aircraft Landing with a Domain Precursor Inflow Method

Journal of Marine Science and Engineering
Flight tests and wind tunnel experiments face difficulties in investigating the impact of aircraft carrier air-wake on the landing process. Meanwhile, numerical methods generally exhibit low overall computational efficiency in solving such problems.

Analysis of Flutter Characteristics for Composite Laminates in Hypersonic Yawed Flow

Aerospace
This paper investigates the flutter characteristics of composite laminates in hypersonic yawed flow using numerical simulations. The governing equations are derived based on Hamilton’s principle and were discretized using the assumed mode method.

Separated flow over bodies of revolution using an unsteady discrete-vorticity cross wake. Part 2: Computer program description [PDF]

A method is developed to determine the flow field of a body of revolution in separated flow. The computer was used to integrate various solutions and solution properties of the sub-flow fields which made up the entire flow field without resorting to a ...

On the Unsteady Behavior of the Flow around NACA 0012 Airfoil with Steady External Conditions at Re=1000

, 2015
Even for the stationary airfoils, due to the boundary and shear layer interactions of upper and lower surface of the airfoils, alternating vortex patterns form and the flow becomes time dependent.
