| Summary |
"A study of the laser holographic interferometer was conducted to compare heat transfer data obtained with the device to standard free convection boundary layer theory. The system studied was an isothermal vertical flat plate. The interferometer was used to obtain fringe patterns of the boundary layer at the plate surface. Data from the holographic interferograms were recorded by making conventional two-dimensional photographs of the holographic images. The optical data are shown to have a good correlation to Von-Karman theory. Values of the boundary layer thickness, temperature distribution, and heat transfer were compared. An attempt was made to probe the boundary layer with a conventional thermocouple in an effort to provide a third type of comparative data. The laser holographic interferometer was shown to be an excellent instrument for obtaining quantitative heat transfer measurements in the gaseous boundary layer"--Abstract, leaf ii. |
