PENGARUH BENTUK PENGARAH ANGIN (DEFLECTOR) TERHADAP KARAKTERISTIK AERODINAMIS KENDARAAN NIAGA (TRUCK)
Abstract: Aerodynamic is a
branch of science which study the effect of wind to an object. Transport
vehicle (truck) is one of the object in this field. A deflector is use to
direct the wind for aerodynamics aspect. The research is conduct in a small
scale wind tunnel with 40 cm x 40 cm cross section and 300 cm length. A truck
model is varied without deflector, flat deflector, convex deflector and concave
delector. The wind speed is varied at 1,9; 2,31 and 3,23 m/s by a fan. U type
manometers with 30o inclination are used to measure height difference (Dh) of
the water column at 3 pointsabove the deflector. The data are used to count the
wind pressure and the wind speed.Aerodynamic performance is described as a
capability to maintain the wind speed at measurement points.The research result
shows that the deflector has effect due to aerodynamics characteristic of truck
model. Convex deflector has the best performance. Flat and concave deflectors
are next.
