Abstract

The University Of Windsor/DaimlerChrysler Fan Test Facility is part of a study to develop a simplified numerical model for predicting the behaviour of automotive cooling fans. The facility could be used to validate computational fluid dynamic software. Three-dimensional velocity vector information is required on planes at specified axial locations downstream from the fan. The facility consists of a 3m x 3m x 3m test chamber, which contains a fan and shroud combination located in the ceiling. The fan is attached to a vertical rotating shaft, which is driven by a variable speed DC motor arrangement. An X-array hot-wire probe is positioned, consecutively, at two downstream locations to determine the 3 components of velocity over the plane. The "ram air" effect is simulated by drawing additional air through the fan using a blower on the exhaust from the test chamber. An orifice plate is used to determine the overall flow rate through the facility. The entire operation is automated using a microcomputer and a multi input/output card. Operating conditions allow for flow rates between 0.28 m3/s and 1.133 m3 /s with pressure differences across the fan of less than 2500 Pa. This thesis outlines the development of the physical facility and the associated computer software used to gather data. Sample results are presented in the form of velocity components, velocity magnitude, and volume flow rate versus pressure performance characteristics.Dept. of Mechanical, Automotive, and Materials Engineering.
