@article{oai:fukuyama-u.repo.nii.ac.jp:00008117, journal = {福山大学工学部紀要}, month = {Dec}, note = {P(論文), The flowfield around a model of the Mars Environmental Survey (MESUR) Pathfinder probe traveling at a speed of Mach 10 was investigated by the electrical discharge method. The shock shape ahead of the capsule was visualized using a technique for visualizing 3-D shock shapes, then the streamline following the shock wave was visualized using a technique for observing streamlines crossing a shock wave. Subsequently, the expansion wave from the capsule shoulder was visualized by applying a technique for observing density changes. The flow pattern behind the capsule was then visualized by applying a technique for observing streamlines near a model surface. Finally, the flow pattern at a small angle of attack near the capsule shoulder was compared with one at zero angle of attack. These experiments qualitatively demonstrate spatial flow structures before and behind the hypersonic re-entry capsule. The techniques used in these experiments, known as the electrical discharge method, enable experimental investigations of spatial flow structures around the hypersonic re-entry capsule, which to date have been quite difficult to perform. These experimental results would be useful in comparing and verifying the results obtained by numerical calculations.}, pages = {157--166}, title = {Flowfield around Hypersonic MESUR Capsule}, volume = {26}, year = {2002} }
