| Summary: | The chassis dynamometer room is one of many extensions in the automotive
laboratory, UTHM, which is one of a few dynamometer rooms available in Malaysia.
Consequently, it becomes highlighted facility to do tests and researches with respect
to vehicle components such as the braking, cooling, and electrical systems. The
major application however is to evaluate engine performance. Ventilation system is
an essential system to reduce the air pollution, thus maintain acceptable indoor air
quality (IAQ) in any chassis dynamometer room. Currently, the room depends on
two types of ventilation: natural ventilation through two windows and a door,
enhanced with mechanical ventilation which is an exhaust fan placed on the top of
the room. Unfortunately, the existing ventilation system is not sufficient to support
activities conducted in the room as was proven in the IAQ study. Therefore in the
current study, results of a computational fluid dynamics (CFD) for air flow and
thermal distribution in the tested room are presented. CFD results expose the
weaknesses of the existing system. Thus, a much better air flow structure and thermal
distribution as required shall be provided by the installation of a new improved
ventilation design as proposed in this study. |
