4. 2. Aerosol deposition to coastal forests: a wind tunnel approach

   Author : Ausra Reinap; Bo L.B. Wiman; Birgitta Svenningsson; Bo Bergbäck; Lise Lotte Sørensen; Linnéuniversitetet; []
   Keywords : NaCl aerosol; dry deposition; climate change; coastal-zone forest; Quercus robur; wind tunnel; edge effect; NATURAL SCIENCES; NATURVETENSKAP; Miljövetenskap; Environmental Science;

   Abstract : Aerodynamically rough surfaces of forests provide for efficient air/ canopy exchange of mass, heat and momentum. In that context, the effects of forest edges come into focus, and therefore, coastal-zone forests constitute aparticular concern. READ MORE

5. 3. Investigations of Flow Conditions in an Automotive Wind Tunnel

   Author : Emil Ljungskog; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind tunnel; Ground simulation; Tangential blowing; CFD simulations; Slotted walls;

   Abstract : As vehicle manufacturers seek to shorten the development time of new models, wind tunnel testing of prototype vehicles needs to be partially replaced by virtual simulations. However, this requires thorough validation of the virtual methods, which is done by comparison to wind tunnel tests. READ MORE

6. 4. Evaluation and modeling of the flow in a slotted wall wind tunnel

   Author : Emil Ljungskog; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD Simulations; Ground Simulation; Uncertainty Quantification; Wind Tunnel; Tangential Blowing; Flow Uniformity; Slotted Walls;

   Abstract : As vehicle manufacturers strive to shorten the development time of new models, an increasing share of the aerodynamic development work is shifted from wind tunnel testing of prototype vehicles to numerical simulations of virtual models. However, comparing measurements from the wind tunnel with numerical simulation data is not straightforward due to several interference effects occurring between the wind tunnel and the tested vehicle.

7. 5. Scaling techniques using CFD and wind tunnel measurements for use in aircraft design

   Author : Karl Pettersson; Arthur Rizzi; Henrik Alfredsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; wind tunnel; scaling; Reynolds number effect; Vehicle engineering; Farkostteknik;

   Abstract : This thesis deals with the problems of scaling aerodynamic data from wind tunnel conditions to free flight. The main challenges when this scaling should be performed is how the model support, wall interference and the potentially lower Reynolds number in the wind tunnel should be corrected. READ MORE
