Dual rotations of rods on thermosolutal convection in a porous cavity suspended by nanoencapsulated phase change materials

The fractional of a time derivative for the incompressible smoothed particle hydrodynamics (ISPH) method is adopted to handle thermal radiation on thermosolutal convection in a porous cavity barred by nanoencapsulated phase change materials (NEPCMs). A novel work on the rotational velocities of two rods during thermosolutal convection of NEPCMs within a novel cavity of two connected circular cylinders is introduced. The management of heat-mass transfer and velocity magnitude inside distinct designed materials below various boundary conditions carries improvements for energy efficiency. The physical factors are thermal radiation Rd=0-3, Fusion temperature ?f=0.05-0.8, Rayleigh number Ra=10(3)-10(6), hot source length L-Hot=0.4-1, Darcy number Da=10(-2)-10(-5), and fractional order parameter a=0.95-1. This study reported the role of thermal/solutal conditions in varying the dual convection flow and heat capacity contour. The lower Da provides an elevated porous resistance which decelerates the nanofluid velocity. The fusion temperature alters a heat capacity contour.
