Abstract

The article investigates the impact of periodic streaming on the stability of multilayered fluids in a porous channel, using viscous potential theory. It analyzes the dynamics of interfacial waves and the effects of velocity, viscosity, and surface tension on stability. The study employs mathematical modeling, perturbation analysis, and the method of multiple scales to derive dispersion relations and stability criteria. Numerical simulations and graphical representations illustrate the effects of various parameters on the system's stability, highlighting the complex interplay between fluid properties and external forces. The findings have practical implications for industries involving lubricants, plastics, and coating processes, where understanding stability is crucial for optimizing performance and preventing failures.
