Hydrodynamics and Fluids Mixing Shock Tube

  • DRIVER & DRIVEN

The shock tube facility has a 5.5″ x 5.5″ internal area and can shock wave strengths up to Mach 2.75 into atmospheric pressure air. It has three main sections; the driver, the driven, and the test sections. The driver section is made of round tube with an 8″ internal diameter and 1 inch wall thickness. The driven and test sections are made of square tube with a wall thickness of 0.75 inches and an internal cross section of 5.5″ by 5.5″. The test section contains window ports that allow the visualization of the fluid dynamics occurring within the tube. It is made of several modular sections that can be rearranged to allow visualization of the fluid dynamics at different times after shock acceleration. The tube has a closed end, trapping the shock pressure within the tube, and creating a reflected shock wave that can be used to accelerate a fluid field for a second time. The end wall has a sapphire window port that allows a laser to illuminate the fluid flow.
