Area of Science:

• Fluid Dynamics
• Magnetohydrodynamics (MHD)
• Heat and Mass Transfer

Background:

• Understanding non-Newtonian fluid behavior in porous media is crucial for industrial applications.
• Magnetohydrodynamics (MHD) effects significantly alter fluid flow dynamics.
• Double diffusion processes influence heat and mass transfer characteristics.

Purpose of the Study:

• To analyze the magnetohydrodynamics (MHD) Carreau fluid flow through a porous medium under double diffusion.
• To investigate the impact of variable thermal conductivity and suction/injection on the fluid flow.
• To explore the influence of various parameters on velocity, temperature, and concentration profiles.

Main Methods:

• Utilized similarity transformations to convert governing equations into dimensionless non-linear ordinary differential equations.
• Employed Maple software for numerical solutions.
• Presented results graphically to illustrate the effects of different parameters.

Main Results:

• Increased porosity parameter was found to reduce the velocity profile.
• Both temperature and concentration profiles were enhanced by increasing the porosity parameter.
• Variable thermal conductivity led to an enhancement in the temperature field, while the Nusselt number showed an opposite trend.

Conclusions:

• The study provides insights into the complex interplay of double diffusion, MHD, and porous media on Carreau fluid flow.
• Findings highlight the significant influence of porosity and variable thermal conductivity on heat and mass transfer.
• The analysis offers valuable data for optimizing processes involving non-Newtonian fluids in porous environments.
