Abstract
The problem of active control of the mechanical equilibrium of an inhomogeneously heated fluid in a thermosyphon is studied theoretically and experimentally. The control is performed by using a feedback subsystem which inhibits convection by changing the orientation of thermosyphon in space. It is shown that excess feedback leads to the excitation of oscillations which are related to a delay in the controller work. In the presense of noise, the oscillations arise even when deterministic description predicts stationary behaviour. The experimental data and theory are in good agreement.
