Abstract

This paper introduces an innovative pressure measurement system for unsteady flow measurement. Unsteady flow is currently one of the hot topics of road vehicles aerodynamics and an inexpensive, simple-to-use tool for its investigation has long been missing. Conventional pressure measurement systems with centralized pressure scanners and long tubings do not satisfy the needs of unsteady phenomena. An approach of miniature MEMS pressure sensors is used instead, whereby the sensors are installed directly on the surface of the body under investigation. This concept not only enables the possibility of unsteady flow measurement but also offers a fast and reliable method of pressure field investigation. Finally, the measurement system was aimed at the specific needs of road vehicle productive testing and provides an effective tool capable of rapid experiment preparation, reliable measurement and simple post-processing.
The newly developed system was tested and validated in different experiments in a specialized test stand and in model scale wind tunnel measurements.
