説明
Possibility to stabilize the oscillatory thermocapillary convection is demonstrated using a proportional feedback control. The feedback control is realized by locally modifying the surface temperature by using the local temperature measured at different locations fed back through a simple control law. The control method was applied in simplified geometries such as the annular configuration and the half-zone for high Prandtl number liquids by means of experiments, numerical simulations, and formulation of a simple model equation system. Successful suppression of the oscillation was obtained especially in the weakly nonlinear regime where the control completely suppresses the oscillations. With a right choice of actuators, even with the local control, it was shown that it is possible to modify the linear and weakly-nonlinear properties of the three-dimensional flow system with linear and weakly nonlinear control.
