EVALUATION OF ENERGY CONVERSION AND STORAGE SYSTEMS FOR VEHICLE'S WIND TURBINE HAZILA BINTI NAYAN A project report submitted in partial fulfillment of the requirement for the award of the Degree of Master of Manufacturing Faculty of Mechanical and Manufacturing Engineering Universiti Tun Hussein Onn Malaysia JANUARY 20 1 5
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 2013. 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.
