Assessing the Aeroacoustic Response of a Vehicle to Transient Flow Conditions from the Perspective of a Vehicle Occupant (2014)
Journal Article
Oettle, N., Sims-Williams, D., & Dominy, R. (2014). Assessing the Aeroacoustic Response of a Vehicle to Transient Flow Conditions from the Perspective of a Vehicle Occupant. SAE International Journal of Passenger Cars - Mechanical Systems, 7(2), 550-558. https://doi.org/10.4271/2014-01-0591

On-road, a vehicle experiences unsteady flow conditions due to turbulence in the natural wind, moving through the unsteady wakes of other road vehicles and travelling through the stationary wakes generated by roadside obstacles. Separated flow struct... Read More about Assessing the Aeroacoustic Response of a Vehicle to Transient Flow Conditions from the Perspective of a Vehicle Occupant.

An Active Turbulence Generation System for the Simulation of Aerodynamic Transients in a Model Wind Tunnel (2014)
Presentation / Conference Contribution
Mankowski, O., Sims-Williams, D., Hunt, A., & Dominy, R. (2014, June). An Active Turbulence Generation System for the Simulation of Aerodynamic Transients in a Model Wind Tunnel. Presented at First International Conference in Numerical and Experimental Aerodynamics of Road Vehicles and Trains (Aerovehicles 1)., Bordeau, France

This paper outlines the creation and validation of an active turbulence generation system (TGS) for the simulation of wind and vehicle-induced transients in a model scale, ¾ open jet, wind tunnel.

Evaluation of the Aerodynamic and Aeroacoustic Response of a Vehicle to Transient Flow Conditions (2013)
Journal Article
Oettle, N., Mankowski, O., Sims-Williams, D., Dominy, R., & Freeman, C. (2013). Evaluation of the Aerodynamic and Aeroacoustic Response of a Vehicle to Transient Flow Conditions. SAE International Journal of Passenger Cars - Mechanical Systems, 6(1), 389-402. https://doi.org/10.4271/2013-01-1250

A vehicle on the road encounters an unsteady flow due to turbulence in the natural wind, unsteady wakes of other vehicles and as a result of traversing through the stationary wakes of roadside obstacles. Unsteady effects occurring in the sideglass re... Read More about Evaluation of the Aerodynamic and Aeroacoustic Response of a Vehicle to Transient Flow Conditions.

Bluff Body Drag Reduction with Ventilated Base Cavities (2012)
Journal Article
Howell, J., Sims-Williams, D., Sprot, A., Hamlin, F., & Dominy, R. (2012). Bluff Body Drag Reduction with Ventilated Base Cavities. SAE International Journal of Passenger Cars - Mechanical Systems, 5(1), 152-160. https://doi.org/10.4271/2012-01-0171

Various techniques to reduce the aerodynamic drag of bluff bodies through the mechanism of base pressure recovery have been investigated. These include, for example, boat-tailing, base cavities and base bleed. In this study an Ahmed body in squarebac... Read More about Bluff Body Drag Reduction with Ventilated Base Cavities.

The Aerodynamic Characteristics of a Fully Deformable Formula One Wind Tunnel Tyre (2012)
Journal Article
Sprot, A., Sims-Williams, D., & Dominy, R. (2012). The Aerodynamic Characteristics of a Fully Deformable Formula One Wind Tunnel Tyre. SAE International Journal of Passenger Cars - Mechanical Systems, 5(2), 1026-1041. https://doi.org/10.4271/2012-01-1166

Competitive aerodynamic performance of a Formula One car relies upon total understanding of the downstream wake of exposed rotating wheels. Sensitivities to the downstream vortices and low stagnation-pressure regions lead to subtle design decisions i...

Reconstruction of the Unsteady Pressure Field in a Low Speed Linear Cascade (2012)
Presentation / Conference Contribution
Förster, F., Sims-Williams, D., & Ingram, G. (2012, December). Reconstruction of the Unsteady Pressure Field in a Low Speed Linear Cascade. Presented at ASME Turbo Expo 2012: Turbine Technical Conference and Exposition, Copenhagen, Denmark

This paper describes investigations into unsteady flow phenomena in a high turning linear cascade with a nominal steady flow. A fast response five hole probe was used to obtain time-accurate measurements. Since a single probe was used to traverse an...

The Bandwidth of Transient Yaw Effects on Vehicle Aerodynamics (2011)
Journal Article
Mankowski, O., Sims-Williams, D., Dominy, R., Duncan, B., & Gargoloff, J. (2011). The Bandwidth of Transient Yaw Effects on Vehicle Aerodynamics. SAE International Journal of Passenger Cars - Mechanical Systems, 4(1), 131-142. https://doi.org/10.4271/2011-01-0160

A vehicle on the road encounters an unsteady flow due to turbulence in the natural wind, the unsteady wakes from other vehicles and as a result of traversing through the stationary wakes of road side obstacles. There is increasing concern about poten... Read More about The Bandwidth of Transient Yaw Effects on Vehicle Aerodynamics.
