Fluid Mixing at Extreme Conditions Laboratory

Texas A&M University College of Engineering

Multiphase Detonation Tube

The multi-phase detonation facility  is designed to investigate detonations in liquid droplet and solid particulate fuels and gaseous oxidizer. The tube itself has a cross section of 2.25″ by 2.25″ (57mm x 57mm) and length of approx 3m and is designed to be capable of handling detonations of a variety of fuel-ox mixtures and initial pressures/temperatures. Its construction consists of an ignition/fill section, 500mm detonation-to-deflagration accelerator section, 1.5m of development section to measure the wave, pizeoelectric transducers to measure pressure/velocity profiles, two test sections with optical through access, and a hydraulically clamped diaphragm loader and expansion/blowdown tank to contain the detonation. The facility has full optical access to directly image the multiphase flow field and reacting fuel droplets and particles via the various method in use in the lab (Laser-illuminated imagery, LIF,PLIF, PDPA particle and droplet sizer, Schlieren, shadowgraphy, Pyrometry, etc.), as well as pressure and temperature diagnostics.
