COMPETITION BETWEEN LID-DRIVEN AND NATURAL CONVECTION IN SQUARE CAVITIES INVESTIGATED WITH A LATTICE BOLTZMANN METHOD
Краткое описание
A lattice Boltzmann method is developed to investigate a situation combining natural and forced lid-driven convection in a two-dimensional square cavity over a very wide range of Rayleigh (Ra) and Reynolds (Re) numbers. The features of dynamic and thermal fields are presented for different Ra and Re to explain the role of Richardson number (Ri) in mixed convection. The flow and heat-transfer characteristics are discussed in both cooperation and opposing cases. Within the scope of this study, the predictive formulas are obtained to describe the heat transfer in terms of relationship between the average Nusselt number (Nu) and the controlling parameters. Different from the Lattice Bhatnagar, Gross and Krook approximation (LBGK) approximation, a lattice Boltzmann model is applied in this work.
