Recent studies on the analysis of the effects of rigid and elastic baffles on heat transfer inside an enclosure.

Baffle type	Authors [ref.] (year)	Convection type	Fluid	Solution method	Problem statement	Main result
Solid	Asl et al. [10]	Natural	Air	Finite volume code	Effect of porous and solid fins in a rectangular enclosure	Porous and solid fins increase average Nusselt up to 41% and 20%, respectively.
Solid	Bendaraa et al. [11]	Natural	Copper-water nanofluid	COMSOL software	Effect of different locations of fins on heat transfer in a square cavity	Adding fins on the adiabatic/cold and hot walls increases and decreases average Nusselt, respectively.
Solid	Menni et al. [12]	Force	Air	Fluent software	Effect of baffle orientation and geometry on the heat transfer in a rectangular channel	The largest variation in Nusselt and skin friction has occurred in the region facing the baffle.
Solid	Keramat et al. [13]	Natural	Air	ANSYS fluent software	Effect of porous fins in H-shape cavity	Average Nusselt for porous fins increases by 60% in comparison to solid fins.
Solid	Li et al. [14]	Natural	Al2O3-water nanofluid	Fortran code	Effect of magnetic field and thermal radiation on the nanofluid around a circular baffle in a square cavity	Increasing the Hartmann and Rayleigh reduced heat transfer and improved Nusselt, respectively.
Solid	Gokulavani et al. [15]	Natural	Air	Finite difference code	Effect of the heated baffle on the fluid in the ventilation cavity	Vertical baffle transfers heat better than horizontal baffle.
Elastic	Ghalambaz et al. [16]	Natural	Air	Finite element code	Effect of horizontal oscillating baffle(s) on the heat transfer in a square cavity	Increasing the amplitude of oscillating baffle(s) significantly enhances Nusselt.
Elastic	Alsabery et al. [17]	Natural	Air	Finite element code	Effect of oscillating baffle(s) mounted on the bottom of the oblique cavity	Baffle(s) has (have) an essential effect on the flow and heat transfer.
Elastic	Raisi and Arvin [18]	Natural	Air	Numerical code	Effect of adiabatic and flexible baffle in the center of the cavity	An increase in Rayleigh increases the elastic baffle deformation.
Elastic	Hussein et al. [19]	Natural	Al2O3-water and Cu-water nanofluid	Fortran code	Effect of baffle length that horizontally attached to the left wall on the heat transfer	Baffle length changes flow field and vortices strength. The longer baffle causes more changes to the flow field.
Elastic	Ghalambaz et al. [20]	Natural	Newtonian fluid	Numerical code	Controlling the natural convection in the L-shape enclosure by flexible baffle	Stiffer baffle inhibits natural convection.
Elastic	Saleh et al. [21]	Natural	Porous medium and incompressible non-Newtonian fluid	Finite element code	Effect of the flexible baffle on the cavity filled with fluid and porous medium	With the rising oscillation amplitude, the heat transfer rate increases exponentially.
