Numerical model to study natural convection in a rectangular enclosure filled with two immiscible fluids

Natural convection in a vertically divided square enclosure by a solid partition into air and water regions

“…A relatively higher Prandtl number was taken for partition. This approximation was taken from Moshkin [18] and Prakash and Koster [19]. Thus, left side of Grashof number was taken as base Grashof number.…”

“…In this context, Nishimura et al [17] performed a numerical work to analyze the natural convection in a rectangular enclosure horizontally divided into fluid and porous regions. Moshkin [18] used finite difference approximation of the Navier-Stokes equations under the Boussinesq-fluid assumption to simulate the flow and heat transfer in a two-layer system of an immiscible fluid. This problem also analyzed by different authors as Prakash and Koster [19,20], Richer [21], Richer and McKenzie [22], Dobretsov and Kyrdyashkin [23], Csereper and Rabinovich [24], Csereper et al [25].…”

Effects of inclination angle on conduction—natural convection in divided enclosures filled with different fluids

“…This case can be referred to cooling problem of internal combustion engines (one side filled with oil and the other side cooling water), cooling of electronic heaters (air in one side and cooling fluid in the other side) or solar collector (air in one side and phase change material to store heat in liquid phase in the other side). To the best of the author's knowledge, there is no study in the literature investigating the natural convection of two different fluid filled enclosures except natural convection in a two-layer system of immiscible liquids by Moshkin [18] and Prakash and Koster [19]. Thus, the main aim of the present study is to investigate the natural convection fully divided with a partition in an enclosure filled with different fluids.…”

“…They indicated that inclination angle has a strong influence on heat transfer. Other studies can be found on natural convection in enclosures with single or multiple partitions in literature [17][18][19][20][21].…”

Mixed Convection in Lid-Driven “T” Shallow Cavity Heated From Bottom and Filled by Two Immiscible Fluids of Air and Al2O3-Water Nanofluid

“…In the horizontal channel with permeable walls, [1] provided an analytical study of the heat transfer problem in the presence of two immiscible fluids with an oscillatory flow. Numerous studies has been developed to discuss certain phenomena that occur in the presence of two immiscible fluids in square or rectangular cavities, which has been taken into account in [2][3][4][5]. The two fluids can be separated with a rigid wall, which is treated by [6][7][8].…”
