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

    Författare :Emil Ljungskog; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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.

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

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

    Sammanfattning : 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. LÄS MER
