A visualization technique is applied to the unsteady separated flow about an autorotatlng flat plate. An unsteady potential model is attempted to predict the pressure loading on the plate as a function of angle of attack. To visualize the flow, a streakline is marked by low density air created by the wake of a heated wire probe. An off-center parabolic mirror Schlieren system detects the density gradient. Due to the highly unsteady nature (in this project, the plate rotates at almost 1,000 r.p.m. for a 10-foot per second freestream velocity) of the flow, high-speed 35mm, single lens reflex shots or 16mm. movie films recorded the image. Timing marks on the movie film provided information of the angular speed of the plate during acceleration to the autorotation speed and at autorotation. The two-dimensional unsteady attached flow model attempts to duplicate the effects of separation by superimposing vortices in the wake, as shown in the flow visualization, and by eliminating terms representing the freestream velocity in the range of 60 to 150 degrees angle of attack. / Applied Science, Faculty of / Mechanical Engineering, Department of / Graduate

Many physical systems can be represented by a regular arrangement of molecules in a lattice structure. Knowing how neighboring molecules in the lattice interact with one another can give great insight into a material's macroscopic behavior. A very popular and effective means of investigating these microscopic interactions is the Ising Model. This model, suggested first by Wilhelm Lenz in 1920 and later expanded by Ernst Ising in 1925, is based on the assumptions that each molecule in a lattice structure can be represented by its spin value (+l or -1) and that only nearest neighbors contribute to the total interaction energy. The Ising Model, which was initially used in the study of ferromagnetic systems, can now be used to study a variety of physical systems. Some of these include antiferromagnetic crystals, binary alloys, DNA, and lattice gasses. / Department of Physics and Astronomy
