The Interaction Between Shock Waves and Complex Geometric Boundary

Based on the Finite Volume Method (FVM) and unstructure grid, the following phenomena are successfully simulated: the interaction of shock wave with slotted plates, the bypass of shock wave through oblique wings, and an applicational examples: the validity of common whirl shelter against shock waves. The results show that the method adopted in the thesis is not only efficacious, but also reliable. An image data processing method numerical interferometry is developed to improve the deficiency of general display of contours. Through this experiment like images created from numerical data, a closer comparison of experimental data with computational predictions can be easily achieved, which provides a better insight into the flow behavior. The combination of a physical interpretation of numerical data and a dynamic comparison of images is found to be very helpful for the investigation of shock wave-complex boundary interactions.
