Abstract

Different laser-light induced dissipative structures arising under various irradiation conditions during oxidation of vanadium in air are discussed. The observed instabilities are explained in terms of hydrodynamics, since the oxidation process takes place in the liquid phase, taking into account the influence of surface tension forces and gravitational effects on liquids of different densities. The decisive role of positive feedback between thermal and hydrodynamic degrees of freedom in the process of instability development is emphasized.
