| Summary: | Researches on car design are closely related to the field of aerodynamics. The
design was done to minimize the drag force. The experimental method was
only used for testing the initial design and the final design. Improvement and
modification were done by using the CFD simulation. The experiments were
done using the Low Speed Wind Tunnel (LSWT) owned by the National
Laboratory for Aerodynamics, Aeroelastics, and Aeroacoustics Technology.
The Reynolds number ranged from 505,225 to 671,528. The research began
with the initial design called JM-5, tested in the LSWT. Modifications were
done throughout the research to achieve the lowest drag coefficient value. In
the end, JM-4v2 became the final design with the lowest drag coefficient value
of 0.202. |
