Development of a background oriented schlieren system

Curtis Paul McAlister


The background oriented schlieren (BOS) flow visualisation method is a relatively new method of determining flow characteristics. The technique offers a significant decrease to the cost and equipment requirements when compared to established flow visualisation techniques. BOS uses computational analysis of images to provide an insight into the features and processes occurring within a flow field. This project aimed to determine the optimal setup for the system, and to investigate the effect of varying contributing parameters within the system on the systems performance as a whole.
