Abstract
The present work introduces numerical simulations based on an incompressible scheme of smoothed particle hydrodynamics (ISPH) method for the thermosolutal convection from an inner I-shaped inside an infinite-shaped cavity embedded by nano-encapsulated phase change materials (NEPCMs). An infinite-shaped enclosure is occupied by a nanofluid and a porous medium. In this work, the heat capacity of a core and shell is used for the overall heat capacity of encapsulated nanoparticles. An inner I-shaped is embedded inside a center of an enclosure and it carries Th and Ch. The simulations are performed for different values of a length of an inner I-shaped L2(0.4≤L2≤1.5), a Stefan parameter Ste(0.2≤Ste≤0.9), a fusion temperature θf(0.05≤θf≤0.95), Darcy parameter Da(10−2≤Da≤10−5), an inclination angle γ(0≤γ≤π/2) and Rayleigh number Ra(103≤Ra≤106). The numerical simulations showed that a fusion temperature θf adjust the situations of a melting solidification zone. Further, the intensity of a melting solidification zone is adjusted by a Stefan parameter. Augmentations of an inner I-shaped length and Rayleigh number are powering buoyancy forces and thus the flow speed, and heat & mass transport are enhanced inside an infinite-shaped cavity. Mean Nusselt and Sherwood numbers are enhanced as I-shaped length and Rayleigh number are powered.
