TWO DIMENSIONAL FLOW QUANTITATIVE VISUALIZATION BY THE HYBRID METHOD OF FLOW BIREFRINGENCE AND BOUNDARY INTEGRATION

摘要

Flow birefringent method and its data processing was reviewed and a new hybrid method offlow birefringence and boundary integration was introduced. The basic equations and boundary conditionssuitable to the hybrid method were derived, and a comparison of the hybrid and other classical methodswas given. Finally as an example, the flow in a step converging tube was analyzed by the given method.
