PCT No. PCT/US94/14890 Sec. 371 Date Apr. 30, 1996 Sec. 102(e) Date Apr. 30, 1996 PCT Filed Dec. 30, 1994 PCT Pub. No. WO95/18419 PCT Pub. Date Jul. 6, 1995The present invention provides a method of restricted space formation for working media motion that can be used to design flow channels for flow of different working media (liquid or gaseous) in simple as well as complex flow channel configurations, for instance in piping and other conduits, heat exchange devices and other fluid flow devices. In one embodiment, a visual test method is used wherein a special relationship to a characteristic wavelength of a flowing fluid is present with respect to at least one of (1) optically active solid particles suspended in a test medium, (2) a wavelength of light to which flowing test medium is subjected, and (3) the depth of the flow channel in a test model. In another embodiment, a fluid flow structure comprising a micro-scale structure and a large-scale structure can be identified from a visual image of flow of test medium through a test model. Information concerning the fluid structure can be used to select a configuration for a flow channel for use in a fluid flow apparatus. In another aspect, a fluid flow apparatus is provided having a fluid channel with a fluid flow boundary surface shaped to correspond to a shape of a fluid flow micro-scale and/or large-scale discrete structure of a flowing fluid. |
