The study numerically simulates the thermosolutal convection of circular rotation of dual circular cylinders inside a combined cavity. The connections among the circular rotation of solid cylinders containing nanofluid plus porous media are modeled by the ISPH method. The findings show that the addition of nanoparticles decreases the nanofluid velocity, while increasing the buoyancy parameter accelerates the nanofluid movements and enhances the mean Nusselt number Nu. The variations of porous levels and Rayleigh numbers also affect the nanofluid flow and thermosolutal convection within the combined cavity.
The thermosolutal convection of circular rotation of dual circular cylinders inside a combined cavity of a circular cylinder on a rectangular shape is numerically simulated by the ISPH method. The combined cavity is occupied by a nanofluid and porous media. Two levels of heterogeneous and homogeneous porous media are considered. The pertinent factors are scaled by nanoparticles parameter (0=f=0.05), levels of porous media(0=?1=?2=1.5), Darcy parameter (10-2=Da=10-5), buoyancy parameter(-1=N=2), Rayleigh number (103=Ra=106), and Lewis number(4=Le=10). The connections among the circular rotation of solid cylinders containing nanofluid plus porous media are modeled by the ISPH method. The main findings demonstrated that combining nanoparticles to %5 declines the nanofluid velocity due to extra viscosity. Increasing the buoyancy parameter accelerates the nanofluid movements and enhances the mean Nusselt number Nu. The variations of porous levels are changing the nanofluid flow and characteristics of heat and mass transfer within a combined cavity. Rayleigh numbers play a significant job in enhancing the nanofluid velocity and thermosolutal convection in a combined cavity.
