Every year, several final year projects take place at the laboratory. Depending on the field of activity, different academic promotors are associated to match the needs of the students works. The proposed topics are mainly dealing with experimental aerodynamics with a large opening to numerical approaches. Generally speaking all these topics are in phase with the possibilities of the wind tunnel (low speed aerodynamics) and its instrumentation.

Industrial applications are welcomed to build and propose new topics for the next academic years (contact T. Andrianne).

TOPIC #1 Development of a parametric aerodynamic model of a micro-drone for performance optimization [attributed]

Promoter: T. Andrianne (ULg-WTL)

Industrial partner: D. Arendt (AEROBOT s.a.)

Fleye is a spherical micro-drone weighing approximately 350g, having a diameter of around 220 mm. It is intended for short-duration aerial filming at low altitudes and speeds. It is made of single propeller within a protective duct. A first prototype has been built and tested in the wind-tunnel (March-April 2015). The R&D activities on that prototype are being finalized and the airframe design is frozen.

WT_FLEYE

The objective of this final year project is to draw the main lines of Fleye 2.0, the next generation, which will be faster and smaller. It will be coupled with a long internship (min 80 days). The bulk of the work will be carried out at the company site and at the wind tunnel laboratory of University of Liège.

TOPIC #2 Development of an accelerated Discrete Vortex Method for unsteady aerodynamic and aeroelastic simulations of bluff-bodies

Promoters: T. Andrianne & V. Terrapon

Industrial partner: –

The objective of this project is to implement a performant 2D Discrete Vortex Method (DVM) method in Matlab. This method consists in a Lagrangian approach where discrete vortical particles are tracked after being shed from the surface of the body. As such, it does not require the meshing of the computational domain and, thus, constitutes an interesting alternative to classical CFD methods.

WTL_DVM_snapshot150

The major drawback of the method is the relatively high computational cost when the number of vortex particules becomes important (typically O(N^2).  Different acceleration techniques exist such as the Tree algorithm and the Fast Multipole method (FMM), which reduces the cost of the velocity calculation to O(N log N) or O(N) operations. This leads to a tremendous reduction in computation time.

The objective of the work is to implement these acceleration techniques in a 2D DVM code and to validate it by comparison with experimental measurements available at the Wind Tunnel Laboratory. Time-resolved PIV and unsteady pressure measurements will be used in order to validate modelisation of the complex aerodynamic phenomenon (flow separation and re-attachment) of the DVM code.

TOPIC #4 Improvement of the aerodynamic behavior of a blended wing body UAV: numerical and experimental investigations [attributed]

Promoter: T. Andrianne (ULg-WTL)

Industrial partner: P.A. Vigano (Aircraft Traders s.a.)

The company Aircraft Traders s.a. is developing an Unmanned Aerial Vehicle (UAV) dedicated to the long distance supervision of ground activities: GuardianEye. This UAV is characterized by a blended wing body geometry (span of 2.2m), including winglets and a propeller located at the back of the aircraft.

The first prototype of the UAV (GE1) is operational and used by the company to perform preliminary flight tests. Another prototype (GE2), 50% larger than the previous one, is currently under development. In parallel of these first prototypes, it is desirable to improve the global performances of the aircraft by a detailed analysis of its aerodynamics. The improved geometry will be named GE+.

WTL_drone_VIGANO

The objective of this final year project is to develop an numerical/experimental framework that leads to the improvement of the capabilities of the GuardianEye: flyability and performances. The activities are shared between numerical analyses and experimental investigations at the WTL of ULg.

TOPIC #5 Design of wind tunnel turning vanes: experimental and computational analysis [attributed]

Promoter: T. Andrianne (ULg-WTL)

Industrial partner: O. Meyer (AEM aero GmbH)

The company AEM aero has an important experience in the design and construction of subsonic aerodynamic wind tunnels. The design of high quality wind tunnels requests a full understanding of the aerodynamic flow through its components. Amongst others, turning vanes are located in the corners of the tunnel to ensure a smooth passage of the flow. Their role is double: reduction of the pressure losses to limit the required power of the driving fan and improvement of the quality of the flow field at the location of the model to be tested.

The objective of this project is to perform experimental (test-bench) and CFD analysis of turning vanes.

Academic year 2014-2015

TOPIC #1 – Numerical and experimental investigations of the flow around the rotor of a spherical micro-drone

Promoters: T. Andrianne and G. Dimitriadis

Industrial partner: D. Arendt (AEROBOT s.a.)

The objective of this final year project is to model numerically the flow around the micro-drone, including the effects of the rotor(s). The modelling will be carried out by means of a vortex lattice unsteady aerodynamic code that has been developed at the Aeroelasticity and Experimental Aerodynamics research group. The code currently only models a single rotor, it will need to be adapted in order to include the second rotor and the fuselage. Compressibility effects may also need to be taken into account. A wind tunnel test campaign is planned in order to validate the simulations results. This project is ideally coupled with an internship within the company.

TOPIC #2 – Model of a Natural Draught Cooling Tower

Promoter: T. Andrianne

Industrial partner: A. Lambert (Laborelec GDF-SUEZ)

The purpose of the work is to estimate the increase of the flow resulting from the addition of aerodynamic modules in the upper and lower part of the cooling tower inlet. This works is carried out in collaboration with Electrabel (GDF-Suez). A CFD model of the cooling tower focusing on the aerodynamics should be created (2D steady simulations are foreseen). A simplified model could be used for the heat transfer between the water and the air (in the rain room, fill and spray zones). These simulations results will be compared with on-site measurements performed by Electrabel in one of its cooling tower.

TOPIC #3 – Modelling of the response of a slender structure to vortex shedding in the atmospheric boundary layer

Promoters: T. Andrianne and V. de Ville de Goyet

Industrial partner: Bureau d’études Greisch

The objective of this work is to design an aeroelastic wind tunnel model representing the dynamic and aerodynamic characteristics of ah high-rise structure with square shape and an aspect ratio of 20×1 (height x side width). This type of structure is prone to undergo Vortex Induced Vibration (VIV) due to the frequency matching between its first bending mode and the vortex shedding process taking place in its wake. In addition, the Atmospheric Boundary Layer (ABL) is also reproduced in the wind tunnel in order to take into account the turbulent response of the structure and the effect of the incoming turbulence on the VIV phenomenon. On top of the experimental works to perform, numerical tool will be developed with the objective to predict the measured displacements of the structure, at the prototype scale. Finally, the codified methods proposed by EC-1994-1 will be applied and its predictions discussed regarding the experimental and numerical results produced through this work.

TOPIC #4 – Unsteady pressure distributions on a high rise building in the atmospheric boundary layer

Promoters: T. Andrianne and V. Denoël

Industrial partner: –

The objective of this work is to investigate the statistic distribution of the pressure distributions around an high rise building measured inside an atmospheric boundary layer wind characterised by non-gaussian wind characteristics. For that purpose pressure measurements will be carried out on a 1/100 scaled model of a BxBx10B model in the wind tunnel.

TOPIC #5 – Development of a wind tunnel-based flight mechanics test platform

Promoters: T. Andrianne and G. Dimitriadis

Industrial partner: –

The objective of this work is to develop an experimental platform dedicated to the flight mechanics analysis of an aircraft. The different aerodynamic derivative and structural parameters of the aircraft will be determined experimentally (static wind tunnel test) or obtained from the literature. The resulting results of the flight mechanics model will be compared to dynamic measurements carried out in the wind tunnel.
