“…The sensor strip pitch is defined by subtracting the reservations for the electronic regions (L electronics ) from the maximum length of the flexible PCB that the manufacturer can produce (L max ), and then evenly distributing it among the number of sensing elements (n), as (1). These parameters can be adjusted based on different design requirements.…”

“…It seeds a fluid with small tracer particles, illuminating the fluid, capturing images of the particles, and then analysing the images to determine the particles movement in the fluid. [1] studied aerodynamic characteristics of a vehicle model using PIV and CFD methods to measure the near wake flow structure. A. Parfett et al [2] used PIV to obtain instantaneous records of the velocity field around an F1 car wheel and described the flow about a smooth wheel rolling along a plane surface.…”

Application of non-pneumatic tire (NPT) has been increased during the last decade. The aerodynamic characteristics of the wheel with NPT has been studied due to significance on improvement of handling and reduction of fuel consumption. In this paper, first, an original NPT model was simulated by CATIA software, and the influence of NPT structural parameters on aerodynamic characteristics was studied by Fluent software. The simulation calculation results showed that: the reduction of tire width and spoke length, and the increase of spoke thickness can effectively decrease aerodynamic coefficient. Then, the MIRA model was used to study the influence of NPT on aerodynamic characteristics of the whole vehicle under driving conditions. Studies showed that: NPT increased the resistance of the whole vehicle, and 63.1% of the resistance at the wheels was provided by the front wheels. Finally, the wind tunnel test was conducted to study aerodynamic characteristics of the optimized NPT model under static conditions and verify the simulation calculation.

While designing sports cars, getting the aerodynamic balance of the vehicle is very important. Aerodynamic elements to create rear downforce are studied extensively while, this research tries to recognize the various ways of developing effective front end down force producing devices. The most widely used add-on devices include the front splitter, canards and underbody vortex generators. CFD simulations are employed to study these devices on the widely acknowledged MIRA fastback model. ANSYS Fluent CFD software was used with the efficient k- ε model to get accurate results while avoiding expensive experimentation costs. Reduction in lift force with the help of these elements generally leads to high drag force. This study aims to find out the most suitable and versatile devices. The average lift decrement on the addition of front aerodynamic elements was ΔC l = 0.0778 while the increase in drag was ΔC d = 0.0393.
