Mixing Layer Facility (small)
Mixing Layer Facility (small)
| The small Mixing Layer Facility is a two stream,
gravity driven, blow down, water flow apparatus. The free-stream fluids
are supplied from two independent reservoirs located about 10 feet above
the test section (see schematic below). The small Mixing Layer Facility
is being used for the investigation of turbulent mixing including the study
of the effects of pertubations on turbulent mixing enhancement.
The dimensions of the test section are 4 cm x 8 cm (height x span) and 35 cm in length. The maximum Reynolds number (based on the shear layer velocity difference and local width) is on the order of 104. Below are two schematics of the flow facility. The upper one shows the overall setup of the Mixing Layer Facility with fluid reservoirs, valves, pumps, and test section. The lower figure depicts the details of the test section and includes an example of a Laser Induced Fluorescence (LIF) application. See the photo gallery of fluid motion for some LIF images.
