Abstract
In our analysis, the Archimedean and thermocapillary mechanisms (or subsystems) are complicated by the superposition of the thermoelectrical subsystem, leading to a new technological opportunity, which is the transport of heat by cellular motion when heating is from above. The interaction of the subsystems determines the properties of the object which is the molten zone. Synergetic properties of the object and its space-time periodicity are governed in particular by the thermoelectric instability and by the thermocapillary stabilization. It follows that the Thermoelectric convention is an example of the interaction of hydrodynamic, electric, and thermal subsystems in a disordered system. When these subsystems interact in an open thermodynamic system, such as a heated liquid film, self- organization takes place and macroscopic space-time structures appear. It follows from synergetic consideration that the resultant cells (deterministic motion) also exist in a certain range of values of the same control parameters. The new mechanism explains why it is possible to transfer heat by convection when a free surface is heated. This problem is important in the formation of melts by laser radiation.
