Fluid–structure coupling mechanism and its aerodynamic effect on membrane aerofoils
Journal of Fluid Mechanics, 2018Fluid–structure interactions of elastic membrane aerofoils are investigated at Reynolds number $Re=10\,000$ and low angle of attack. The dynamics of the fluid and membrane coupled system are solved using direct numerical simulation (DNS), where the geometry and boundary conditions were applied using a boundary data immersion method.

Physics of Fluids, 2023
This study focuses on the aerodynamic nonlinearity and flow field phenomenology of structure-motion-induced dynamics in fluid–structure interactions (FSI), which is essential for response prediction. Through dynamic-meshing large-eddy simulations with near-wall resolution, the nonlinear aerodynamic damping in the still wind has been isolated by forced ...

Aerodynamic Shape Optimization Using “Turbulent” Adjoint And Robust Design in Fluid Mechanics
2015This article presents adjoint methods for the computation of the first- and higher-order derivatives of objective functions \(F\) used in optimization problems governed by the Navier–Stokes equations in aero/hydrodynamics. The first part of the chapter summarizes developments and findings related to the application of the continuous adjoint method to ...

Examination of aerodynamic parameters of fluid controlled mechanical thrust-vectoring nozzle
Journal of Applied Science and Technology, 2009The aerodynamic parameters of fluid controlled mechanical thrust vectoring nozzle have been computed to establish the relationships for improving the nozzle design. While a nozzle with exit Mach number (M) of 3 was used as case study, other values of exit M were also considered for comparison.

Some Applications of Combined Asymptotics and Numerics in Fluid Mechanics and Aerodynamics
1993Diverse examples are discussed illustrating the power of combining asymptotics and numerical solution procedures. Problems in transonic flow are treated as well as an unusual application occurring in paper manufacturing and magnetic recording. A recurrent theme in these applications is the simplification and clarification of the essential issues by the

International Journal of Structural Stability and Dynamics
After installing lamps on hangers, large amplitude vibrations are likely to occur. To explore the aerodynamic interference mechanism of lamps installed on tandem hangers, this study is based on computational fluid dynamics (CFD) and implements the fluid–structure interaction (FSI) numerical simulation of tandem hangers through user-defined functions ...
