Numerical investigation of frequency-amplitude effects of dynamic morphing for a high-lift configuration at high Reynolds number

Abderahmane Marouf, Yannick Bmegaptche Tekap, Nikolaos Simiriotis, Jean-Baptiste Tô, Jean-François Rouchon, Yannick Hoarau, Marianna Braza

The purpose of this study illustrates the morphing effects around a large-scale high-lift configuration of the Airbus A320 with two elements airfoil-flap in the take-off position…

Experimental and CFD study of slotted Krueger flaps aerodynamics in critical locations

Robert Kulhánek, Zdeněk Pátek, Petr Vrchota, Pavel Procházka, Vaclav Uruba

Some recent effort showed that usage of Krueger flaps helps to maintain laminar flow in cruise flight. Such flaps are positioned higher relative to the chord to shield the leading…

Investigation of performance of small wind turbine blades with winglets

Michal Kulak, Michal Lipian, Karol Zawadzki

This paper aims to discuss the results of the performance study of wind turbine blades equipped with winglets. An investigation focusses on small wind turbines (SWTs), where the…

Magnus effect for roll-decoupled canards on a spinning body of revolution

Daniel Klatt, Alina Mielke, Christian Mundt

Spinning slender bodies are affected by lateral Magnus forces and moments when exposed to cross-flow. The effects occurring for spinning bodies of revolution in combination with…

Assessment of stress-blended eddy simulation model for accurate performance prediction of vertical axis wind turbine

Taurista Perdana Syawitri, Yufeng Yao, Jun Yao, Budi Chandra

The aim of this paper is to assess the ability of a stress-blended eddy simulation (SBES) turbulence model to predict the performance of a three-straight-bladed vertical axis wind…

Incipient stall characterization from skin-friction maps

Massimo Miozzi, Alessandro Capone, Christian Klein, Marco Costantini

The purpose of this study is the characterization of the dramatic variation in the flow scenario occurring at incipient stall conditions on a NACA0015 hydrofoil at moderate…

Casing-groove optimisation for stall margin in a transonic compressor rotor

Ahmad Fikri Mustaffa, Vasudevan Kanjirakkad

This paper aims to understand the aerodynamic blockage related to near casing flow in a transonic axial compressor using numerical simulations and to design an optimum casing…

Vehicle aerodynamic simulation analysis and research on bumpy road

Zheng Xin, Donghai Su

In order to certify the testing of vehicle Cd on the real road can be replaced by the much simplified steady-state simulation process inside wind tunnel.
