Soret Effect and Chemical Process on MHD Oscillatory Flow in a Physiological Fluid.

Area of Science:

• Fluid dynamics
• Biomedical engineering
• Chemical kinetics

Background:

• Magnetohydrodynamics (MHD) describes fluid motion in magnetic fields.
• Arterioles are small blood vessels crucial for regulating blood flow.
• Soret effect involves thermal diffusion, influencing concentration gradients.

Purpose of the Study:

• Investigate the impact of chemical reactions and Soret effects on MHD oscillatory flow in porous arterioles.
• Analyze the influence of physical parameters on blood flow dynamics.
• Provide insights for controlling blood flow during surgical procedures.

Main Methods:

• Mathematical modeling of flow governing equations based on specific assumptions.
• Derivation of exact analytical solutions for velocity, temperature, and concentration profiles.
• Graphical presentation of numerical computations for key physical parameters (Grashof, Reynolds, Magnetic, Soret numbers).

Main Results:

• Blood viscoelasticity significantly reduces blood flow (BF) velocity.
• The Lorentz force, influenced by the magnetic field parameter, increases BF velocity.
• Chemical and Soret reactions impact the oscillatory flow characteristics.

Conclusions:

• The study provides a theoretical framework for understanding complex blood flow behavior in arterioles.
• Results offer potential applications in controlling blood flow during surgical interventions.
• Highlights the interplay between fluid properties, external fields, and transport phenomena.
