Description | Diffused back illumination with grayscale intensity threshold to indicate liquid region. Vapor-phase beam steering also persists downstream as discussed in [1,2]. The light source is a pulsed LED with only 50 ns pulse duration to freeze the flow. Blue liquid boundaries, stored as Matlab binary files, are available to download . See readme notes. | Mie scatter illumination from the side with high resolution. Laser illumination side is from the bottom of the image. Similar borders are used to derive liquid length vs time.Interpret with caution because of non-uniform lighting and light extinction. Borders, stored as Matlab binary files, are available to download . See readme notes. | Schlieren movie obtained simultaneously with Mie-scatter movie. Movie shown with and without corrections for background schlieren effects from the ambient. | Schlieren movie shows border of vapor region. Movie shown with and without corrections for background schlieren effects from the ambient. Vapor boundaries, stored as Matlab binary files, are available to download . Load files within Matlab to access variables. See readme notes for more information. |
