ABSTRACT

This project involved the design of a wind turbine system and the evaluation of

aerodynamics performance of pickup truck with wind turbine system. Pickup truck

with wind turbine models was developed using Solid Work sohare . Computer

simulation (using Ansys software) was carried out to investigate the effects of wind

turbine installation on aerodynamics of the pickup truck. Three pickup truck models

with different wind turbine system positions i.e in front of the fiont bumper, on top of

the hood and on top of the roof plus one model without the wind turbine system were

simulated. The study proved that the position of the wind turbine system will change

the characteristic of the air flow around the pickup truck body and affects the

aerodynamic performance of the pickup truck. Without the wind turbine, the

coefficient of drag Cd for the pickup truck model was 0.345, which was computable to

that of stated in Toyota Hilux specification.. As for the model with wind turbine, the

Cd obtained were 0.345, 0.349. 0.353 and 0.344 for the case of fiont bumper, hood,

roof and under pickup truck respectively. Extended fiont bumper of a pickup truck

was not significantly affect the aerodynamics performance of the pickup truck. The Cd

obtained for the case of extended bumper was slightly lower than of the original

bumper height.

ABSTRAK

Projek ini melibatkan rekabentuk sistem turbin angin untuk trak pickup dan penilaian

prestasi aerodinamik trak pickup dengan sistem turbin angin. Trak pickup dan

sistem turbin angin dimodelkan dengan menggunakan perisian Solidwork 20 1 3.

Perisian Ansys Fluent digunakan untuk mengkaji kesan pemasangan

sistem turbin angin dan kesan pemasangannya terhadap kecekapan aerodynamic trak

pickup. Tiga model Trakpichp dengan kedudukan system turbin angin yang berbeza

(di hadapan bumper depan , di atas hud dan di atas bumbung) dan satu model tanpa

sistem turbin angin disimulasikan. Kajian ini membuktikan bahawa kedudukan

pemasangan sistem turbin angin akan mengubah ciri aliran udara di sekitar badan

trak pickup dan memberi kesan kepada prestasi aerodinamik kereta. Tanpa turbin

angin, nilai Cd bagi trak pickup ialah 0,345 sesuai dengan spesifikasi Toyota Hilux.

Bagi model trakpickup dengan turbin angin, Cd diperolehi ialah 0,345, 0,349. 0,353

dan 0,344 bagi kes terbin angin dipasang pada atas bumper, atas hood, di atas

bumbung dan di bawah trak pickup. Bumper depan sebuah trak pickup yang

direndahkan tidak memberi kesan ketara terhadap prestasi aerodinamik trak pickup

tersebut. Nilai Cd yang diperolehi adalah rendah bagi bumper yang direndahkan

daripada ketinggian bumper asal.
