The magnetic field on thermosolutal convection in an annulus between two super ellipses

The current study deals with the impacts of an inclined magnetic field on the double-diffusive convection of the nano-encapsulated phase change materials (NEPCM) suspended in an annulus between two super ellipses. A novel shape between two super ellipses having the positive numbers n = 3/2 and a = b. The controlling transformed equations are solved by employing the (ISPH) method. The heat/mass source with variable length is put on the left side of an annulus. Impacts of (Ha = 0 - 40), (gamma = 0 degrees - 90 degrees), (theta(f) = 0.05-0.95), (phi = 0.01 - 0.04), (L-x = 0.1 - 1), (Ste = 0.1 - 0.8), and (Ra = 10(3) - 10(5)) on the melting/solidification zone and heat/mass transfer performance are investigated. It was remarked that the melting/solidification zone shifts nearly to the heat/mass source according to a growing on Ha. The L-x induces an improvement of the heat/mass transmission and nanofluid movements within an annulus. Increasing the theta(f) is working well in enhancing the melting/solidification zone and make it much closer to the heater within an annulus, and it boosts the nanofluid velocity by 4.24%. Increasing phi to 0.04 strengthens the melting/solidification zone and declines the nanofluid velocity by 14.68%. An augmentation in Ra powers the nanofluid speed, heat/mass transport, and melting/solidification zone within an annulus. Average (Nu) over bar, and average (Sh) over bar are decreasing as Ha and L-x are increased.

Automated summary

This study investigates the impacts of an inclined magnetic field on double-diffusive convection. The results indicate that the magnetic field causes the melting/solidification zone to shift towards the heat source. Increasing other parameters improves heat/mass transfer and nanofluid movement.
