An experimental study on the instability of a detached Stewartson layer, using an annular, rotating tank with flat, rigid upper and lower boundaries, showed an instability to steady vortices at a critical Reynolds number, arranged in a global mode structure along the shear layer. Increasing the Reynolds number resulted in successive transitions to lower(More)
PURPOSE Analysis is performed of the geometry of a Hertel exophthalmometer to determine the intrinsic error of reading that results from using the instrument in the manner that the manufacturer intended. Recommendations for improvement of the design and/or use of the instrument are made based on the findings. METHODS A schematic drawing of the(More)
