...Abdeslam Omara; Mouna Touiker; Abderrahim Bourouis Purpose This paper aims to consider numerical analysis of laminar double-diffusive natural convection inside a non-homogeneous closed medium composed of a saturated porous matrix and a clear binary fluid under spatial sinusoidal heating/cooling...

...Nirmal Kumar Manna; Nirmalendu Biswas; Pallab Sinha Mahapatra Purpose This study aims to enhance natural convection heat transfer for a porous thermal cavity. Multi-frequency sinusoidal heating is applied at the bottom of a porous square cavity, considering top wall adiabatic and cooling through...

... ranging of 0 ≤ T_m ≤ 1 and keeping Ra = 10⁶. Practical implications The results can be used in the cooling of electronic components, thermal storage system and in heat exchangers. Originality/value The choice of consideration of sinusoidal heating and density...

...Huey Tyng Cheong; S. Sivasankaran; M. Bhuvaneswari Purpose The purpose of this paper is to study natural convective flow and heat transfer in a sinusoidally heated wavy porous cavity in the presence of internal heat generation or absorption. Design/methodology/approach Sinusoidal heating...
