1. 6. Experimental study of the turbulent flow in a plane asymmetric diffuser

   Författare :Olle Törnblom; KTH; []
   Nyckelord :fluid mechanics; wind-tunnel. Burbulence; turbulence modelling; earsm; asymmetric diffuser; boundary layer;

   Sammanfattning : The separating turbulent flow in a plane asymmetric diffuseris investigated experimentally. The considered flow case issuitable for fundamental studies of separation, separationcontrol and turbulence modelling. The flow case has beenstudied in a specially designed wind-tunnel under wellcontrolled conditions. LÄS MER

3. 7. Under-body and Diffuser Flows of Passenger Vehicles

   Författare :Ture Jesper Marklund; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bluff bodies; Vehicle aerodynamics; CFD; Wake flow; Boundary layer;

   Sammanfattning : Energy efficient vehicles will be required to meet future emission and fuel consumption requirements. Customers require reduced fuel consumption due to increasing fuel prices and the environmental issues, are drivers to reduce CO2. LÄS MER

5. 9. Experimental and computational studies of turbulent separating internal flows

   Författare :Olle Törnblom; Arne V. Johansson; Michel Stanislas; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; turbulence; flow separation; turbulence modelling; asymmetric diffuser; boundary layer; PIV; vortex generator; separation control; Fluid mechanics; Strömningsmekanik;

   Sammanfattning : The separating turbulent flow in a plane asymmetric diffuser with 8.5 degrees opening angle is investigated experimentally and computationally. The considered flow case is suitable for fundamental studies of separation, separation control and turbulence modelling. LÄS MER

7. 10. Flow facility design and experimental studies of wall-bounded turbulent shear-flows

   Författare :Björn Lindgren; KTH; []
   Nyckelord :fluid mechanics; wind.tunnels; asymmetric diffuser; turbulent boundary layer; flow structures;

   Sammanfattning : The presen present thesis spans a range of topics within thearea of turbulent flows, ranging from design of flow facilitiesto evaluation aluation of scaling laws and turbulence modelingdeling aspects through use of experimental data. A newwind-tunnel has been designed, constructed and evaluated at theDept. of Mechanics, KTH. LÄS MER
