| 201 | Deep depth undex simulator | US480180 | 1983-03-29 | US4495809A | 1985-01-29 | Robert R. Higginbotham; Alexander Malakhoff |
| A deep depth underwater simulator is illustrated for determining the dual effects of nuclear type underwater explosion shockwaves and hydrostatic pressures on a test vessel while simulating, hydrostatically, that the test vessel is located at deep depths. The test vessel is positioned within a specially designed pressure vessel followed by pressurizing a fluid contained between the test and pressure vessels. The pressure vessel, with the test vessel suspended therein, is then placed in a body of water at a relatively shallow depth, and an explosive charge is detonated at a predetermined distance from the pressure vessel. The resulting shockwave is transmitted through the pressure vessel wall so that the shockwave impinging on the test vessel is representative of nuclear type explosive shockwaves transmitted to an underwater structure at great depths. | ||||||

| 204 | Method for recording flow boundary layers in liquid media | US236234 | 1981-02-20 | US4361644A | 1982-11-30 | Gerd Urban; Heinrich Opitz; Gert Mages |
| The disclosed method relates to a method for recording flow boundary layers in liquid media by photochemical means. According to the invention, surfaces which can be developed in a plane and to which a photographic film sheet is cemented are exposed under steady-state conditions to the flow of a liquid medium containing a dissolved agent reacting with the photo gelatin layer. The liquid medium may contain agents furnishing HS-ions or agents capable of dissolving silver halide or reducing silver halide. If a photographic film sheet is used, the silver ions of which are reduced to silver, the flow exposure is performed with an agent having oxidizing and dissolving action. With the method disclosed, half-tone photograms of flow boundary layers in liquids can be recorded. | ||||||

| Using an array of optical sensors affixed to measure interactions on a surface of an object, in combination with a specially configured personal computer, dynamic mapping of interaction is provided. One application maps washover of an object towed in a large body of water. Data are collected on optical characteristics of the interaction such as reflectivity at a boundary. For example, in one embodiment the reflectivity at an optical fiber/seawater boundary is compared to that of an optical fiber/air boundary and dynamic measurements made using an optical time domain reflectometer (OTDR). These data are then processed using specialized software to yield representation of the dynamics (spatial and temporal) of selected washover events on a surface of interest. The system specifically provides a real-time representation of washover, including two and three-dimensional visualization of washover, as well as recording selected data for future use. Methods of employment of the system are also provided. | ||||||
