Thermosolutal convection of a sloshing wavy rod in a partial layer porous cavity mobilized by a nanofluid

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 [Formula: see text] and it carries [Formula: see text] and [Formula: see text]. The rigid cavity walls are fixed, adiabatic (horizontal walls), and [Formula: see text] and [Formula: see text] (vertical walls). The measurements of pertinent parameters are the Soret number ([Formula: see text] Sr [Formula: see text]), nanoparticles parameter ([Formula: see text]), Rayleigh number ([Formula: see text] Ra [Formula: see text]), sinusoidal function ([Formula: see text]), Dufour number ([Formula: see text] Du [Formula: see text]), a slope angle of a magnetic field ([Formula: see text]), Hartmann number ([Formula: see text]), and Darcy parameter ([Formula: see text] Da [Formula: see text]). 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 [Formula: see text].
