摘要: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 T h and C h . The simulations are performed for different values of a length of an inner I-shaped L 2 ( 0.4 ≤ L 2 ≤ 1.5 ) , a Stefan parameter S t e ( 0.2 ≤ S t e ≤ 0.9 ) , a fusion temperature θ f ( 0.05 ≤ θ f ≤ 0.95 ) , Darcy parameter D a ( 10 − 2 ≤ D a ≤ 10 − 5 ) , an inclination angle γ ( 0 ≤ γ ≤ π / 2 ) and Rayleigh number R a ( 10 3 ≤ R a ≤ 10 6 ) . The numerical simulations showed that a fusion temperature θ f 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.
