Summary: | Proton Saga is one of the most successful sedan cars in Malaysia. The
aerodynamics of this car can be defined as bad because the box shape gives a great
value of drag coefficient. The improvement of the aerodynamics of Proton Saga car
can reduce the fuel consumption because the power needed to withstand the drag
force created is decreased. Economical effective wool tufts method is use to analyze
the airflow of Proton Saga car with vortex generator. The increase of pressure
distribution on the rear window surface of the car makes the flow separation to delay.
The aerodynamics improves with the changes of most turbulence flow into laminar
flow. The prediction that can be made that the drag force created decrease
proportionally with the drag coefficient. This paper presents the analysis of the effect
of vortex generator usage on delaying flow separation of Proton Saga car
experimentally. |
