Abstract
The investigation reported in this paper is dealt about the steady-state
laminar flow and heat transfer of a lid driven staggered cavity with the
heated block. Based on the aspect ratio (AR = H/L = 0.5, H/L = 1, H/L = 2)
three different block shapes are introduced for numerical experiments. The
solid block with no slip and stationary wall condition is considered and it
is located at the geometric center of the cavity. The simulations are
carried out for Reynolds numbers 50, 100, 200, 300, 500, and 1000 and
temperature of the block is 300 K. A clock-wise momentum is converged to the
fluid, by the two driving lids on the top and bottom side of the cavity,
lids are set into an anti-parallel wall motion. The upper lid moves to the
right, while the lower one to the left, both are consider as same
velocities. The results are found to be in good agreement with existing
published results. It was found that the dynamics and the structure of the
primary vortex and the corner vortices were strongly affected by the
Reynolds number. The investigation clearly describes that increasing the
Reynolds number values the overall drag coefficient decreases, similarly the
value of average Nusselt number also increases with an increasing Reynolds
number for all the values of different blocks under studied. The study
reveals the important flow physics such as flow separation, boundary-layer
and recirculation. The results will be beneficial for similar situation
occur in many industrial problems.
