in the past few decades, tremendous emphasis has been placed on the importance of incorporating better designs for road vehicles. Not only has this been done with regard to the shape of the overall body of the vehicle, the various components and features of the vehicle which lead to undesirable effects have undergone a lot of redesigning. 1 As the need for fuel saving increases by the day, there has been a lot of focus on modifying certain features on road vehicles in order to alleviate this problem. By re-designing various components such as rear-view mirrors, the wheels, door handles and antennas, progress has been made in reducing the overall drag coefficient of road vehicles which thereby reduce the amount of fuel consumed in order to traverse the same distance at the same

Re-designing door handles to reduce aerodynamic drag in road vehicles

32nd AIAA Applied Aerodynamics Conference

Ever-rising fuel costs necessitate design of fuel-efficient vehicles. Consequently, modern vehicle manufacturers are focused on designing low aerodynamic drag vehicles which would in-turn reduce the fuel consumption. This study analyses the contribution of external rear-view mirrors to the total drag force and the overall sound pressure level at the A, B and C pillars, while optimising the external rear-view mirror design accordingly. Solid Works renditions of external rear-view mirror models mounted on a reference luxury sedan were analysed using a commercially available computational fluid dynamic package ANSYS FLUENT. A different approach was followed to carry out the empirical flow visualisation and predict sound pressure levels. The aerodynamic characterisation of the vehicle was done utilising the widely used shear stress transport turbulence model, while the analysis of wind noise and the contributing vortices employed a large eddy simulation. This approach significantly reduced computational time without compromising on accuracy.
