Abstract
In order to reveal the wake structure's characteristics effectively and then provide the basis to improve the body shape, considering shortcomings of traditional test instruments we introduced the concept of virtual instrument, and developed a virtual instrument system based on hot-wire anemometer to measure automotive wake velocity in the automotive wind-tunnel by means of LabVIEW program. With this system we made an experiment to gain the wake velocity distribution behind one certain kind of passenger car made in China, and the results are in accordance with those of the former research, which validate the virtual instrument system.
