... in a tilted square cavity, which was composed of a solid partition immersed in a porous medium and subjected to sinusoidal heating. In their numerical study, Magherbi et al. [ 12 ] investigated entropy generation resulting from laminar double-diffusive natural convection within an inclined square cavity...

... the temperature of the opposite vertical wall is maintained constant. The results are given for a range of varied parameters as Rayleigh number ( 5 × 10 3 ⩽ Ra ⩽ 10 6 ) , cavity aspect ratio ( 1 ∕ 6 ⩽ A ⩽ 8 ) , and period of the sinusoidally heated wall ( 1 ⩽ τ ⩽ 1600 ) . The amplitude of oscillation ( a = 0.8...
