Prediction and Comparison of low-Reynolds Airfoil Performance

Vincent François-Charles Rolin, Eric Sauvageat

This semester project is aiming to compare different airfoils in order to select the most promising one as blade shape for scaled the straight-bladed giromills used in wind tunnel experiments. For this matter, a large amount of steady-state CFD-simulations ...

The impact of variable building height on drag, flow and turbulence over a realistic suburban surface

Marc Parlange, Marc Calaf Bracons, Marco Giovanni Giometto, Andreas Christen

In realistic urban environments, where buildings experience variable heights, the tallest structures have a disproportional impact on drag, mean flow and turbulence. Although wind-engineering studies document well the effects of individual high-rise buildi ...

Turbulent-laminar patterns in plane Poiseuille flow

Tobias Schneider, Tobias Klaus Kreilos

Turbulent-laminar banded patterns in plane Poiseuille flow are studied via direct numerical simulations in a tilted and translating computational domain using a parallel version of the pseudospectral code Channelflow. 3D visualizations via the streamwise v ...

Computational analysis of the effects of a boundary layer ingesting propulsion system in transonic flow

Vladislav Mantic Lugo

Continuous requirements for more efficient aircrafts lead to the design and analysis of novel propulsion configurations, with an example being the boundary layer ingestion. The complexity and integration challenges in such aircraft synergistic propulsion s ...

High Voltage Pulsed DBD Effects on the Aerodynamic Performances and on the Shock Buffet

Christoph Hollenstein, Peter Ott, Pénélope Leyland, Philip Peschke

The applications of surface dielectric barrier discharge plasma actuators, (DBD), have known a considerable interest recently in the field of flow control. In general, such actuators consist of two electrodes separated by an insulation covering the lower e ...

Experimental Investigation of Pulsed Dielectric Barrier Discharge Actuators in Sub- and Transonic Flow

Christoph Hollenstein, Peter Ott, Pénélope Leyland, Philip Peschke, Sami Goekce

Experiments were conducted in order to investigate the ability of nanosecond pulsed dielectric barrier discharge (ns-DBD) actuators to control flow on airfoils in subsonic and transonic flow (up to Ma1 = 0.75, Re = 1.35 • 10^6). A NACA 0015 profile equippe ...

Tailoring the time-dependent recovery of shape memory polymers

John Christopher Plummer, Charly David Azra

On application of heat, shape memory polymers (SMPs) are able to revert to a primary shape from a secondary shape induced by mechanical deformation. It may be desirable to induce shape recovery at controlled rates under quasi-isothermal conditions, e. g. i ...

Aero Engine Flow Control by Surface Discharge Plasma

Christoph Hollenstein, Peter Ott, Pénélope Leyland, Philip Peschke, Sami Goekce

Experimental investigations and numerical modeling with the objective to study the effects that surface discharge plasmas can provoke on aerodynamic flow situations, including high speed flows present in aero-engines, are undertaken at EPFL. The actuator’s ...
