Hydromagnetic Flow Dynamics in Immiscible Fluid Systems

Hydromagnetic flow dynamics in immiscible fluid systems examines the interaction between electrically conducting fluids that remain phase-separated and externally applied magnetic fields. At the interface of two immiscible layers, magnetic forces modify shear stresses, alter velocity profiles and influence heat and mass transfer. Key parameters include the ratio of magnetic to viscous forces, interfacial tension and fluid conductivity. Recent advances combine analytical, numerical and experimental techniques to reveal how induced magnetic fields and viscous dissipation govern flow stability, mixing efficiency and thermal management. Applications span enhanced oil recovery, magnetic drug targeting, phase-change cooling circuits and microfluidic mixers. By controlling field strength, orientation and pulse frequency, researchers achieve tunable interfacial transport, opening routes to energy-efficient process design and novel materials synthesis.

Research from Nature Portfolio

Recent studies have examined the role of particle morphology in hybrid nanofluids flowing through inclined ducts. By embedding carbon-based nanoparticles in silicon oil, researchers demonstrated that the shape factor of anisotropic particles markedly enhances both velocity fields and convective heat and mass transfer driven by thermal diffusion (Soret effect) and viscous dissipation. Analytical solutions reveal optimal lamina-shaped additives for maximum skin-friction reduction and heat-transfer augmentation.

Another investigation has focused on unsteady magnetohydrodynamic Couette flows of two immiscible conducting fluids in a rectangular channel subject to an inclined magnetic field and axial electric field. Using Laplace transforms and numerical inversion, the study characterised the evolution of velocity, induced magnetic field and temperature profiles. Results highlight the interplay between field inclination and viscous heating in controlling interfacial shear and thermal gradients.
