Natural Convection at Different Prandtl Numbers in Rectangular Cavities with a Fin on the Cold Wall
The natural convection in differentially heated rectangular cavities with a fin attached to the cold wall was investigated numerically. The top and the bottom horizontal walls of the cavities were insulated while their left and the right vertical walls were maintained at a constant temperature Th and Tc, respectively with Th > Tc. The governing equations written in terms of the primitive variab...

متن کاملNumerical Study of Entropy Generation for Natural Convection in Cylindrical Cavities
In this paper, an enhanced computational code was developed using finite-volume method for solving the incompressible natural convection flow within the cylindrical cavities. Grids were generated by an easy method with a view to computer program providing. An explicit integration algorithm was applied to find the steady state condition. Also instead of the conventional algorithms of SIMPLE, SIM...
متن کاملNumerical Simulations of Natural Convection Flow in a Rectangular Cavity under Transient Boundary Conditions
This work is aimed at presenting numerical predictions regarding unsteady natural convection in a rectangular cavity. The flow in the buoyancy-driven cavity of 7 : 1 aspect ratio is numerically analyzed for water (Pr = 3.77) which is exposed to hot and cold vertical plates with periodic temperatures. The results are obtained for three different variable Rayleigh numbers sets whose maximum value...
متن کاملA lattice Boltzmann model for natural convection in cavities
We study a multiple relaxation time lattice Boltzmann model for natural convection with moment–based boundary conditions. The unknown primary variables of the algorithm at a boundary are found by imposing conditions directly upon hydrodynamic moments, which are then translated into conditions for the discrete velocity distribution functions. The method is formulated so that it is consistent wit...
