Abstract
This paper deals with thermo-solutal convection by the oriented fins inside a cavity mobilized by a nanofluid. The three fins are located horizontally in the cavity's center surrounded by a rotating square shape. ISPH method carries the circular rotation of the embedded square shape over the oriented fins. Three distinct thermal/solutal conditions of an inner shape including adiabatic (C1), hot (C2), and cold (C3) are conducted. The configurations of the oriented fins in improving thermo-solutal convection are investigated. It is indicated that the expanded fins length supports the rate of heat/mass transfer and delivers a greater overall heat/mass transfer. The lower nanofluid velocity is found at an expanded fins length, adding extra nanoparticles, extra Hartmann number, and cold condition (C3). Adding extra nanoparticles to 20% slows down the nanofluid velocity by 55.28% Increasing the Soret number to two enhances the nanofluid velocity by 69.47%. The circular rotation of an inner shape changes the patterns of nanofluid movements and circulations of temperature and concentration within a cavity. The magnetic field is working effectively at an extra Hartmann number for shrinking the nanofluid velocity and declines the heat/mass transmission in a cavity.
