Abstract
This work discusses the dual diffusion of a sloshing wavy rod in a nanofluid-filled cavity. The top zone of a cavity is suspended by a porous medium. The boundary treatment in the ISPH method employs a kernel renormalization function. The wavy rod sloshes by an excitation frequency x = a sin(omega t) and it carries T-h and C-h. The rigid cavity walls are fixed, adiabatic (horizontal walls), and T-c and C-c (vertical walls). The measurements of pertinent parameters are the Soret number (0 <= Sr <= 2), nanoparticles parameter (0 <= phi <= 0.1), Rayleigh number (10(3) <= Ra <= 10(6)), sinusoidal function (0.1 <= lambda <= 1), Dufour number (0 <= Du <= 1.5), a slope angle of a magnetic field (0 degrees <= gamma <= 90 degrees), Hartmann number (10 <= Ha <= 50), and Darcy parameter (10(-2) <= Da <= 10(-5)). The performed simulations revealed that the nanofluid flow is accelerated by the Sort number, the sloshing of the rod, and the sinusoidal wavy of the rod. Besides, the dual convection is enhanced by the sinusoidal wavy function and the sloshing of the rod. There is almost no nanofluid flow in a top porous zone of a cavity when Da <= 10(-4).
