Influence of Inclined Magnetic Field, Mass Diffusion and Thermal Radiation Factors on the Flow of Silver Nanoparticles in MHD Blood Inside a Wave Tube

Article Preview

Abstract:

This study systematically investigates the flow characteristics and wall flux evolution of silver nanoparticles in MHD blood flow under the synergistic effects of an inclined magnetic field, thermal radiation, and mass diffusion. Using a cylindrical polar coordinate system and assuming long wavelength and low Reynolds number, the numerical analysis explores the influence of key parameters such as nanoparticle volume fraction, magnetic field tilt angle, magnetic field parameter, radiation absorption parameter, Brinkman number, Schmidt number, and Strouhal number on the flow velocity, temperature, concentration distribution, and wall fluxes. The results indicate that increasing the volume fraction of nanoparticles from 1% to 8% enhances the fluid's viscosity and thermal conductivity, reducing the peak flow velocity by 17.76% and the maximum temperature by 44.76%, while simultaneously increasing the peak concentration by 33.73%. Increasing the magnetic field tilt angle from 0° to 45° significantly enhances flow velocity through synergistic effects between the Lorentz force and fluid dynamics, boosting the maximum flow velocity by 43.29%. The increase in Strouhal number leads to higher peak concentration values. This study reveals, for the first time, the transport and fluid regulation mechanisms of silver nanoparticles under multi-field coupling conditions. It provides critical theoretical support for optimizing drug delivery, tumor hyperthermia, and diagnostic and therapeutic strategies for vascular diseases.
