The Imaging Of A Schock Wave Within A Supersoniclow-Pressure Gas Flow Using Opticalmethods
MetadataShow full item record
Using Environmental Scanning Electron Microscope (ESEM), which uses high gas pressure within the specimen chamber instead of vacuum, allows us to study samples containing water, samples with high capacity and live biological samples. It is because of the lack of the need to freeze the sample to sublimate the water from it. However, the behavior of the pumped gas in low pressures is not well mapped to be the low-pressure gas flow simulations considered adequately precise for applying on ESEM. To increase the precision of simulations, it is possible to use optical methods for imaging the shock wave within the differentially pumped chamber because of its uniqueness.
