lattice boltzmann simulation of egm and solid particle trajectory due to conjugate natural convection

The purpose of this paper is to investigate the egm method and the behavior of a solid particle suspended in a twodimensionalrectangular cavity due to conjugate natural convection. a thermal lattice boltzmann bgk model is implemented tosimulate the two dimensional natural convection and the particle phase was modeled using the lagrangian–lagrangian approach wherethe solid particles are treated as points moving in the computational domain as a result of the fluid motion. entropy generation due toheat transfer irreversibility, isotherms, streamlines and nusselt numbers were obtained and discussed. total entropy generations invarious cases are also reported and optimum case is presented based on minimum entropy generation.
