Available in PDF, EPUB and Kindle. Book excerpt: A new technique for water tunnel flow visualization is based upon the use of a newly developed type of material--neutral-density, bi-liquid foams or 'polyaphrons'. These materials are small, spherical globules of one liqund encapsulated in a thin film of another liquid. It is now possible to make bi-liquid foams when the units are of micron or submircon size, and may be spherical or polyhedral depending upon the relative concentration of oil to water. They are easy to see and photograph in water and they can also be dyed to a variety of intense colors. In this two part study, polyaphrons were used for flow visualization in water tunnel tests of combustors. First, various formulations of the polyaphrons were made to optimize aphron size and density for water tunnel testing. Second, the best polyaphrons were used for flow visualization of real, prototype combustor model. Tests were conducted at 22.5 gpm. This corresponds to Re sub D=23,900, when D is the swirler diameter. Tests showed that polyaphron material proved easy to handle when injected through small tubes and the amount and ratio of injection was easy to control. No clogging of any kind was ever encountered. The pure material broke-up into clumps upon injection. A 50/50 mixture of water polyaphron eliminated clumping. Injection of polyaphrons was also directly compared with the more usual dye injection. Polyaphrons are ideal seeding material for Laser Doppler Velocimetry in water tunnels.

Available in PDF, EPUB and Kindle. Book excerpt: With contributions from some of the world's leading experts, the second edition of this classic reference compiles all major techniques of flow visualization and demonstrates their applications in all fields of science and technology. A new chapter has been added that covers flow visualization applications in large wide tunnels for airplane and automobile testing. Several important examples of applications are included. A second new chapter details the use of infrared (IR) cameras for detecting and observing the boundary layer transition in industrial wind tunnels and flight testing of commercial transport airplanes. A final new chapter has been added on multiphase flow and pulsed-light velocimetry.

Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation has been made of secondary flow in a 90 degree corner. The tests were run in a water tunnel at low speed (approximately 0.3 ft. per sec.) with emphasis on an attempt to visualize the embedded vortices in the laminar flow. The Reynolds number range was 11,000 to 52,500 per foot; the corner model was 9.75 in. wide by 48 in. long. The model was aligned in the tunnel so that no streamwise pressure gradient was present. Flow visualization was by means of hydrogen bubbles and dye. None of the streak-line examined with either the bubbles or the dye showed any indication of the presence of secondary motion in the first 18 inches of the corner. This is not believed to be conclusive since the vortices may exist at other distances along the corner (the limit here was imposed by the flow visualization apparatus used) or may be poorly developed in the initial length examined.
