Aerodynamics in automobiles
drag reduction:
how to reduce air resistance
-> can increase the energy efficiency
reduce the area that against the wind
there is a coefficent for desciribe the resistance
increase the projected area
add some holes/ slots in the fender
decrease the airflow on the wheels
add airflow guide , to increase the airflow underneath
guided airflow on the front bumper; blow the light
lift vs downforce
add wings on the back of the car to increase the downforce
refine the diffuser to increase the air speed on the bottom
overall: Sills outer (underneath the doors at the side of the car) to decrease the unfavourable airflow under the car from the side, increase the downforce
revise the hood of the car to increase the downforce
heat distribution
add holes/ slots on the hood
Futures
new research method
noise problem caused by airflow
turbulance
antana/ small holes on the car body to induce the shrieking noise
noise caused by the sealing parts
To decrease the noise
seal the A pillar; refine the airflow around A pillar
interior enviroment
Stability
viberation/ noise
direction stability/ turn
the overall refinement of the car body
streamlined design
flattered chassis: decrease the airflow time/ increase speed/ increase the downforce
