| Summary: | A motorcycle windshield protects motorcyclist from wind and external
environment from making direct contact to the upper body extremities while riding.
The windblast that has direct contact with the motorcyclist is considered to be a
laminar flow. However, in the event of poor streamlining, the windshield would trap
the turbulence instead and creates a higher dynamic pressure which affects its overall
aerodynamic functionality. This study was aimed at investigating the different designs
of windshield to minimize dynamic pressure to signify good aerodynamics
characteristics. ANSYS-Fluent workbench was used to simulate the flow and optimize
the streamline. It was observed that windshield with slot had lower performance
compared to the design without slot due to the air passage through the slot that would
subsequently alter the streamline and make the turbulence wake and output dynamic
pressure to be higher. Consequently, the design with a smaller surface area would
perform better due to less stagnation points |
