This cone is in fact the extension of the boundary layer that develops within the nozzle body (section 2). In figure 3, a cone can be clearly seen below the nozzle exit. Shadow images were taken at 75000 frames per second.
Flir A65: 640×512 30 fps thermal machine vision camera. A high-speed camera (FASTCAM-ultima APX RS Photron ) was used to observe the spray. Capable of 10000+ fps at reduced resolution (256×256). Up to 20 commonly used configurations can be saved to memory for future operation.A single flexible sixteen foot (5 meter) cable allows thelightweight camera head easy access to any location. Photron Fastcam Ultima APX: 1024×1024 2000 fps color CMOS camera. A user selectable Region Of Interestђ function enables theactive image area to be defined in steps of 128 pixels wide by 16 pixels high to allow the most efficient use of frame rate, image resolution and memory capacity for any event.
BENEFITS The FASTCAM-X 1024 PCI from Photron is the worldsfirst PC-based high-speed imaging system to provide 1,000 frames per second (fps) recording at full mega pixel image resolution.Utilizing the same super light sensitive 10-bit CMOS sensor as the > Variable speed resolutions,including:1,024 x 1,024-pixels at 1,000 fps 512 x 512-pixels at 3,000 fps 27,000 fps at 128 x 128-pixels 109,500 fps at reduced resolutionGlobal shuttering to 2ҵs,independent frame rate selectedExpandable memory offers several different configurations(PCI card and memory daughter PCB still fit in a single PCI slot) providing a wide range of record times:2GB for 1.6 seconds at 1,000 fps full resolution 4GB for 3.08 seconds at 1,000 fps full resolution6GB for 4.6 seconds at 1,000 fps full resolution8GB for 6.2 seconds at 1,000 fps full resolution 12GB for 9.2 seconds at 1,000 fps full resolution 16GB for 12.3 seconds at 1,000 fps full resolution24GB for 18.5 seconds at 1,000 fps full resolutionFits in single PCI slot,regardless of memory configurationselectedCamera is connected to PCI card via 16 foot (5m) flexible cable User defined Region Of Interestђ Ultima APX with large 17 micron squarepixels, the 1024 PCI operates from 60 to 1,000 fps at full1,024 x 1,024-pixels resolution, and at reduced resolution all the way to a top speed of 109,500 fps.A global electronic shutter, operating down to 1.5microseconds ensures even the fastest moving objects are frozen, blur free, in every image. The high-speed cameras were run at their maximum resolution of 1024 × 1024 pixels and captured vector fields at a. Processing of the data was performed using LaVision Inc.’s DaVis 8 software. These images are selected from the original 1,000 fps recording. The S-PIV system consisted of two Photron Fastcam Ultima APX high-speed cameras, a Photonics DM20-527 dual-head laser, and a LaVision Inc. 91 FASTCAM-APX Detailed settings for the FASTCAM-APX are shown in five sections General.
All vehicles are subjectedto rigorous crash and sled tests,every one of which must be recorded at 1,000 frames per second for the engineers to analyze to see how the vehicle and dummy occupants interact.
