| Popis: | Finite-amplitude convection in a plane, horizontal, exothermic fluid layer in the presence of a static gravitational field and longitudinal high-frequency oscillations is investigated. Nonlinear regimes established after the loss of stability are studied. A numerical finite difference procedure is used. The flow configurations are determined, along with the nonlinear hydrodynamic and heat-transfer characteristics. Maps of the regimes are plotted for the superposition of thermovibrational and thermogravitational excitation mechanisms. It is shown that the intensification of heat transfer by fully developed convection lowers the fluid temperature and raises the threshold of thermal explosion. |
