Abstract
The fractal dimension and Lyapunov exponent are measured for the chaotic flow in a thermal convection loop. With a one dimensional map of the flow, it is demonstrated that the dynamics of the thermosyphon is similar to that of an NH{sub 3} ring laser. Various characteristics of the thermosyphon are measured, such as temperature and frequencies of the flow versus heating. Attempts to stabilize the no-motion state with a feedback controller is described, and the effect of time delay in the controller is analyzed. 32 refs, 69 figs
