RESEARCH DIRECTED TOWARD THE DESIGN AND FABRICATION OF A SOLAR ATMOSPHERIC DISHPAN EXPERIMENT.

Abstract

The motion of a conducting fluid confined within the annular space between two rotating concentric cylinders and subjected to an approximately radial temperature gradient was studied as a function of: the angular velocity of the cylindrical system, the applied annular temperature gradient and the radius of the inner cylinder. Both single lobe Hadley regimes and multiple lobe Rossby regimes were observed. The results of each experiment (with a given radius of the inner cylinder) are presented as a two-dimensional field map in which the observed lobe number is mapped at measured points in the angular velocity-temperature gradient field. Additional fluid motion experiments were performed to study the effects on these results of reversing the temperature gradient, applying a magnetic field parallel to the axis of rotation, employing various fluids and changing the geometry of the outer and inner surfaces (in contact with the fluid). Again, Hadley and Rossby regimes were observed in many cases. (Author)
