The low Reynolds number aerodynamics is important to investigate for micro air vehicle applications. The current paper covers numerical simulations to present the downstream …
We reveal the effects of sweep on the wake dynamics around NACA 0015 wings at high angles of attack using direct numerical simulations and resolvent analysis. The influence of …
Linear modal instabilities around post-stall swept finite wings at low Reynolds numbers Page 1 J. Fluid Mech. (2022), vol. 944, A6, doi:10.1017/jfm.2022.420 Linear modal instabilities around …
The study of an airfoil at low Reynolds number regime was found to be a typical problem where the inception of bifurcations leads the flow evolution from a stationary or periodic …
While tapered swept wings are widely used, the influence of taper on their post-stall wake characteristics remains largely unexplored. To address this issue, we conduct an extensive …

In the present study, we have numerically investigated Carreau and Newtonian fluid flow over a stationary National Advisory Committee for Aeronautics 0012 airfoil using a sharp …
The present paper investigates the planar flow past a circular cylinder for Reynolds numbers between 1000 and 10 000. The flow is studied as a dynamical system, so the present …
